Possession in Welsh

In Brief

Welsh does not normally use a direct equivalent of the English verb have. Instead, it says that something “is with” a person: Mae gen i gar in a common northern pattern, or Mae car gyda fi in a common southern pattern, both meaning “I have a car.” To say my car, your car, or his/her car, Welsh uses forms such as fy nghar i, dy gar di, and ei gar e / ei char hi; the change at the start of the noun is part of the pattern.

Overview

Possession covers two closely related jobs. The first is saying that someone has something: a car, two sisters, a question, or some time. The second is identifying an owner inside a noun phrase (a group of words built around a thing or person), as in “my cat” or “her house.” Welsh handles both jobs differently from English.

For “have,” Welsh uses bod (“to be”) together with a preposition meaning roughly “with” or “by.” This may feel unusual to an English speaker, but the practical beginner rule is simple: learn Mae gen i ... or Mae ... gyda fi as a complete frame rather than translating “I + have” word by word.

Possessive words such as fy (“my”), dy (“your”), and ei (“his” or “her”) also trigger mutation—a regular change to the first consonant of the following word. This is an A1 topic, but it builds directly on the nasal mutation. At first, concentrate on the forms for “I,” “you,” “he,” and “she”; the complete system is included below for reference.

How It Works

Saying “have” with gan

A very common pattern, especially associated with northern spoken Welsh, is:

Mae + form of gan + person + thing possessed

The form of gan changes according to the person. A preposition that changes this way is called an inflected preposition—in plain terms, its ending tells you who is involved.

Person	Positive pattern	Meaning
i	Mae gen i gar.	I have a car.
ti	Mae gen ti gar.	You have a car.
e/fe or o/fo	Mae ganddo fe/fo gar.	He has a car.
hi	Mae ganddi hi gar.	She has a car.
ni	Mae gynnon ni gar.	We have a car.
chi	Mae gynnoch chi gar.	You have a car.
nhw	Mae ganddyn nhw gar.	They have a car.

Spoken forms vary by region, so you may meet slightly different spellings or pronunciations. Gen i and gen ti are especially useful forms to recognise immediately.

The possessed item normally follows the person:

• Mae gen i amser. — I have time.
• Mae gan Aled gi. — Aled has a dog.
• Mae ganddi hi ddau frawd. — She has two brothers.

Notice gan Aled with a named person, but gen i with “me.” In this possession pattern, the possessed noun normally undergoes soft mutation: car → gar, cath → gath, and ci → gi. This is why Mae gen i gar contains gar, not car. A vowel-initial word such as amser shows no visible change, and number phrases may bring their own mutation patterns.

Saying “have” with gyda

A second everyday pattern, especially associated with southern spoken Welsh, uses gyda (“with”):

Mae + thing possessed + gyda + person

Person	Example	Meaning
fi	Mae car gyda fi.	I have a car.
ti	Mae car gyda ti.	You have a car.
fe/e	Mae car gydag e.	He has a car.
hi	Mae car gyda hi.	She has a car.
ni	Mae car gyda ni.	We have a car.
chi	Mae car gyda chi.	You have a car.
nhw	Mae car gyda nhw.	They have a car.

Gydag is used before a vowel sound in careful forms, as in gydag e. In speech, local forms vary. You do not need to choose one pattern as the only “correct” Welsh: learn the form used by your course, community, or teacher, while training yourself to understand both.

Questions and negatives

Welsh changes mae in this construction to make a question or a negative. For a present-tense yes/no question, use oes. For a negative, use does ... ddim.

Statement	Question	Negative
Mae gen ti feic.	Oes gen ti feic?	Does gen ti ddim beic.
Mae amser gyda chi.	Oes amser gyda chi?	Does dim amser gyda chi.

In the negative, ddim comes before the possessed noun, so compare positive Mae gen ti feic with negative Does gen ti ddim beic. The safest approach is to learn these as complete patterns rather than trying to make them from the English sentence word by word.

Short answers agree with oes, not with English “do":

• Oes gen ti gar? — Oes. — Do you have a car? — Yes.
• Oes arian gyda ti? — Nac oes. — Do you have money? — No.

Possessive forms before a noun

Welsh possessives usually come before the noun and are often reinforced by an echoing pronoun after it. An echoing pronoun repeats the owner: compare the i at the end of fy nghath i. English does not do this, but it is normal and helpful in Welsh.

Owner	Before the noun	Mutation or change	Example
my	fy	nasal mutation	fy nghath i — my cat
your (singular, familiar)	dy	soft mutation	dy gar di — your car
his	ei	soft mutation	ei dŷ e — his house
her	ei	aspirate mutation	ei thŷ hi — her house
our	ein	no consonant mutation; h- before a vowel	ein car ni, ein henw ni — our car, our name
your (plural or polite)	eich	no mutation or added h-	eich tŷ chi, eich enw chi — your house, your name
their	eu	no consonant mutation; h- before a vowel	eu plant nhw, eu henw nhw — their children, their name

The most visible beginner patterns are:

Original	“my” with fy	“your” with dy	“his” with ei	“her” with ei
car	fy nghar i	dy gar di	ei gar e	ei char hi
tad	fy nhad i	dy dad di	ei dad e	ei thad hi
pen	fy mhen i	dy ben di	ei ben e	ei phen hi
brawd	fy mrawd i	dy frawd di	ei frawd e	ei brawd hi
gardd	fy ngardd i	dy ardd di	ei ardd e	ei gardd hi

The contrast between “his” and “her” deserves special attention. Both use ei, but “his” triggers the soft mutation, while “her” triggers the aspirate mutation. The final e/fe/fo or hi removes any doubt:

• ei gar e — his car (car → gar)
• ei char hi — her car (car → char)

The aspirate mutation only has a visible effect on p, t, c, which become ph, th, ch. With many other consonants, the spelling does not change, so the echoing hi is particularly useful: ei brawd hi means “her brother.”

Do not add the definite article y (“the”) between a possessive and its noun. Say fy nghar i, not fy y car i. If an adjective describes the noun, it normally stays after the noun and before the echoing pronoun: fy nghar newydd i (“my new car”).

Examples in Context

Welsh	English	Note
Mae gen i gar.	I have a car.	Common gan pattern; especially associated with the north.
Mae car gyda fi.	I have a car.	Common gyda pattern; especially associated with the south.
Oes gen ti amser heddiw?	Do you have time today?	Present yes/no question.
Does gen i ddim arian parod.	I do not have any cash.	Negative with does ... ddim.
Mae ganddi hi ddau o blant.	She has two children.	Third-person feminine form of gan.
Mae ci gyda nhw.	They have a dog.	The possessed item comes before gyda nhw.
Dyma fy nghath i.	This is my cat.	fy causes nasal mutation: c → ngh.
Ble mae dy gar di?	Where is your car?	dy causes soft mutation: c → g.
Mae ei dŷ e ger yr ysgol.	His house is near the school.	“His” causes soft mutation: t → d.
Mae ei thŷ hi ger y parc.	Her house is near the park.	“Her” causes aspirate mutation: t → th.
Mae ein plant ni yn yr ardd.	Our children are in the garden.	No consonant mutation after ein.
Beth yw eich enw chi?	What is your name?	eich does not add h before the vowel in enw.
Mae eu ffrindiau nhw yng Nghymru.	Their friends are in Wales.	The final nhw echoes the owners.
Mae fy nghar newydd i yma.	My new car is here.	The adjective comes before the echoing pronoun.

Common Mistakes

Translating “have” with a made-up ordinary verb

• Wrong: Dw i have car.
• Right: Mae gen i gar. / Mae car gyda fi.
• Why: Welsh normally expresses possession through a “be + with” construction. Learn the whole Welsh frame instead of inserting an English verb.

Mixing the two basic word orders

• Wrong: Mae gyda fi car. (as a beginner’s blend of the two taught frames)
• Right: Mae gen i gar. / Mae car gyda fi.
• Why: The common teaching patterns place car after gen i but before gyda fi. Local speech has additional variants, but keeping these two frames separate gives you a reliable starting point.

Forgetting the mutation after a possessive

• Wrong: fy cath i; dy car di
• Right: fy nghath i; dy gar di
• Why: fy triggers nasal mutation, while dy triggers soft mutation. The possessive and the changed noun should be learned together.

Treating ei as unambiguously “his” or “her”

• Wrong: assuming ei car alone must mean one gender
• Right: ei gar e (“his car”); ei char hi (“her car”)
• Why: Both meanings begin with ei. Mutation and the echoing pronoun identify the owner.

Adding y after a possessive

• Wrong: fy y tŷ i
• Right: fy nhŷ i
• Why: A possessive already makes the noun phrase definite. Welsh does not insert “the” as English might in the separate phrase “the house of mine.”

Answering an oes question with ydw

• Wrong: Oes gen ti feic? — Ydw.
• Right: Oes gen ti feic? — Oes.
• Why: A short answer normally repeats the form of bod used in the question. A question beginning with oes takes oes or nac oes.

Usage Notes

The labels “northern” for gan and “southern” for gyda are useful orientation, not rigid borders. Speakers encounter both through education, media, travel, and mixed communities. There is also variation inside each region. Consistency matters more than trying to imitate every local form at once: produce the pattern taught in your learning environment and learn to recognise the other one.

Welsh pronouns have regional variants. For “he,” you may hear e, fe, o, or fo, and these choices affect forms such as ganddo fe/fo and echoing possessives such as ei gar e/fo. They do not change the underlying possession rule.

Echoing pronouns are extremely common in speech because short possessive words can be reduced and because ei alone does not clearly distinguish “his” from “her.” Careful written Welsh may omit an echo where the meaning is already clear, but forms such as fy nghar i and ei char hi are natural models for learners. In rapid colloquial speech, the first possessive may itself be shortened or less audible; recognise such speech gradually, but use the full forms while establishing the mutation pattern.

English uses “have” for many meanings beyond literal ownership: relationships, illnesses, experiences, meals, and obligations. Welsh does not map all of these automatically onto gen i or gyda fi. Some do work naturally—Mae gen i ddwy chwaer (“I have two sisters”)—while others use a different idiom. Learn health and fixed expressions as complete phrases rather than assuming every English “have” has the same Welsh structure.

Beyond the Basics / Advanced Use

You do not need to master the following details at A1, but they make the system easier to recognise in real Welsh.

Other tenses

The possession frame is not limited to the present. Change the form of bod, while the rest of the construction remains recognisable:

• Roedd gen i feic pan o'n i'n blentyn. — I had a bike when I was a child.
• Bydd gen i fwy o amser yfory. — I will have more time tomorrow.
• Basai gen i gar petawn i'n gyfoethog. — I would have a car if I were rich.

The exact spoken forms vary, but the important insight is that Welsh changes “be,” not a separate verb meaning “have.”

A possessor after the noun

Welsh can place a name or another noun directly after the thing possessed:

• car Siân — Siân’s car
• tŷ fy rhieni — my parents’ house
• enw'r plentyn — the child’s name

There is no word corresponding to English of in these examples. The first noun is normally not preceded by the article: car Siân, not y car Siân, when the whole phrase means “Siân’s car.” This compact noun-plus-possessor structure is common in both speech and writing.

Emphatic ownership and “belong to”

When ownership itself is being stressed, Welsh can use eiddo:

• Mae'r car yn eiddo i Siân. — The car belongs to Siân.
• Fi sy'n berchen ar y beic. — I am the one who owns the bike.

These are not replacements you need for everyday Mae gen i .... They are useful when the point is legal ownership, contrast (“it is mine, not yours”), or the verb “belong.”

Possessives beyond ownership

The same fy/dy/ei/ein/eich/eu pattern is later used before verb-nouns (verb forms that can function rather like English “-ing” forms) to express objects:

• Mae hi'n fy ngweld i. — She sees me.
• Dw i'n dy helpu di. — I am helping you.

Here fy and dy do not mean literal ownership. The familiar mutation-and-echo pattern has been extended to mean “me” and “you.” This is one reason possession is an important foundation for Welsh object pronouns.

Practice Tips

1. Build two parallel sets of cards. On one side write Mae gen i goffi and on the other Mae coffi gyda fi. Swap in five useful nouns so that you learn both patterns without mixing their word order.
2. Practise mutations in four-way groups. Start with car and say fy nghar i, dy gar di, ei gar e, ei char hi. Repeat with tad and pen. Saying the owner at the end helps connect each mutation to its meaning.
3. Turn statements into questions and negatives. Change Mae gen ti amser into Oes gen ti amser? and Does gen ti ddim amser. This practises possession and the present forms of bod together.
