Conjunctions and Connectors in Welsh

Overview

Conjunctions and connectors are the glue that holds complex sentences together. At the A2 level, mastering common Welsh conjunctions allows you to express reasons, conditions, contrasts, and sequences — moving beyond simple sentences into more natural, flowing speech.

Some Welsh conjunctions trigger mutations, which is an important detail to learn alongside their meanings. The most frequently used conjunctions are "a/ac" (and), "ond" (but), "achos/oherwydd" (because), "pan" (when), "os" (if), and "felly" (so/therefore).

How It Works

Common Conjunctions

Welsh	English	Mutation?
a / ac	and	Aspirate (of p, t, c)
ond	but	None
achos / oherwydd	because	None
pan	when	Soft mutation
os	if	None
er	although	None
felly	so, therefore	None
neu	or	Soft mutation
tra	while	None (with "bod")
cyn	before	Soft mutation (with "i")
ar ôl	after	None (with "i")

"A" vs "Ac"

• "A" before consonants: bara a chaws (bread and cheese)
• "Ac" before vowels: te ac oren (tea and orange)
• "A" triggers aspirate mutation: c→ch, p→ph, t→th

Examples in Context

Welsh	English	Note
Dw i'n mynd achos mae'n braf.	I'm going because it's fine.	Reason
Pan fydda i'n barod...	When I'm ready...	Time with mutation
Os wyt ti eisiau...	If you want...	Condition
Mae hi'n oer ond yn sych.	It's cold but dry.	Contrast
coffi a the	coffee and tea	"A" + aspirate: te → the
Dw i ddim yn dod, felly cer di.	I'm not coming, so you go.	Consequence
Mae e'n dal neu'n fyr?	Is he tall or short?	Alternative
Er bod hi'n oer, es i am dro.	Although it was cold, I went for a walk.	Concession
Cyn i fi fynd, rhaid gorffen.	Before I go, I must finish.	Sequence
Ar ôl bwyta, aethon ni am dro.	After eating, we went for a walk.	Sequence

Common Mistakes

Forgetting aspirate mutation after "a"

• Wrong: bara a caws
• Right: bara a chaws
• Why: "A" (and) triggers aspirate mutation of p, t, and c.

Using "pan" without mutation

• Wrong: pan bydda i'n barod
• Right: pan fydda i'n barod
• Why: "Pan" triggers soft mutation of the following verb.

Confusing "achos" and "oherwydd"

• Wrong: Neither is wrong
• Right: Both mean "because." "Achos" is more colloquial, "oherwydd" more formal.
• Why: They are synonyms with different register levels.

Usage Notes

Welsh conjunctions operate somewhat differently from English in clause structure. For example, "pan" (when) requires the future tense form of "bod" when referring to future events: "pan fydda i'n barod" (when I will be ready), even though English uses the present tense.

"Er" (although) is often followed by "bod" constructions: "er bod hi'n oer" (although it is cold). This pattern is covered in more detail at B1-B2 levels.

Practice Tips

1. Combine simple sentences: Take two simple sentences and join them with different conjunctions to see how the meaning changes.

2. Focus on mutation triggers: Make a note of which conjunctions trigger mutations and practice them specifically.

3. Listen for conjunctions: In Welsh audio, listen for "ond," "achos," "os," and "pan" as anchors to understand sentence structure.
