Verb Conjugation Groups in Romanian

Overview

Romanian verbs are organized into four conjugation groups based on the ending of their infinitive form. Understanding these groups is a foundational A1 skill because it allows you to predict how regular verbs will behave when conjugated — rather than memorizing every verb form individually, you learn the patterns for each group and apply them systematically.

This system is inherited from Latin, which also had multiple conjugation classes. Among modern Romance languages, Romanian preserves four distinct groups, making it similar to Italian in this regard. French and Spanish have three groups each. The good news is that the group system is highly systematic: once you know which group a verb belongs to, you can conjugate most regular verbs within that group by following a consistent set of endings.

Of course, some of the most common verbs in any language are irregular — a fi (to be), a avea (to have), a face (to do/make) — and these must be memorized separately. But the conjugation group system covers the vast majority of verbs you will encounter and provides a reliable framework for learning new ones.

How It Works

The Four Conjugation Groups

Group	Infinitive Ending	Example Verb	Meaning
I	-a	a cânta	to sing
II	-ea	a vedea	to see
III	-e	a merge	to go
IV	-i / -î	a dormi / a hotărî	to sleep / to decide

Present Tense Endings by Group

Person	Group I (-a)	Group II (-ea)	Group III (-e)	Group IV (-i)
eu	cânt	văd	merg	dorm
tu	cânți	vezi	mergi	dormi
el/ea	cântă	vede	merge	doarme
noi	cântăm	vedem	mergem	dormim
voi	cântați	vedeți	mergeți	dormiți
ei/ele	cântă	văd	merg	dorm

Key Observations

Group I is the largest and most productive. Most new verbs entering Romanian (including loanwords) are assigned to Group I. If you need to guess a conjugation, Group I is the safest bet.

The 1st singular and 3rd plural often share the same form. This is a pattern across all groups, similar to sunt for a fi. Context disambiguates.

The 3rd singular and 3rd plural differ. Unlike the 1st singular / 3rd plural overlap, the 3rd singular has its own distinct ending in each group.

Stem changes can occur. Some verbs undergo vowel changes in certain persons (e.g., a dormi → eu dorm but el doarme — the o becomes oa before e). These stem alternations are predictable once you learn the common patterns.

How to Identify the Group

Remove the initial a (the infinitive marker) and look at the final vowel:

If the infinitive is...	It belongs to...
a + stem + a (e.g., a cânta)	Group I
a + stem + ea (e.g., a vedea)	Group II
a + stem + e (e.g., a merge)	Group III
a + stem + i or î (e.g., a dormi, a hotărî)	Group IV

Examples in Context

Romanian	English	Note
Eu cânt un cântec.	I sing a song.	Group I — a cânta
Tu lucrezi acasă.	You work at home.	Group I — a lucra
El vede un film.	He watches a movie.	Group II — a vedea
Noi mergem la școală.	We go to school.	Group III — a merge
Eu dorm bine.	I sleep well.	Group IV — a dormi
Ei cântă frumos.	They sing beautifully.	Group I — 3rd pl. same as 1st sg.
Voi vedeți muntele?	Do you see the mountain?	Group II — 2nd pl.
Tu mergi repede.	You walk fast.	Group III — 2nd sg.
Copiii dormesc.	The children sleep.	Group IV — irregular 3rd pl. form
Ea învață română.	She learns Romanian.	Group I — a învăța
Noi citim o carte.	We read a book.	Group IV — a citi
Voi plecați mâine?	Are you leaving tomorrow?	Group I — a pleca

Common Mistakes

Applying Group I endings to verbs from other groups.

• Wrong: Eu vedă (treating a vedea like Group I)
• Right: Eu văd.
• Why: Each group has its own set of endings. Identify the group from the infinitive before conjugating.

Confusing Group II (-ea) and Group III (-e).

• Wrong: Assigning a vedea to Group III.
• Right: A vedea ends in -ea, making it Group II. A merge ends in -e, making it Group III.
• Why: The difference between -ea and -e is subtle but determines which endings to use.

Ignoring stem changes within a conjugation.

• Wrong: El dormi. (using the infinitive stem unchanged)
• Right: El doarme. (stem vowel change o → oa)
• Why: Many verbs have predictable vowel alternations in certain persons. These must be learned alongside the basic endings.

Forgetting that 1st singular and 3rd plural overlap.

• Wrong: Being confused when cânt appears without a pronoun.
• Right: Cânt = "I sing" or "they sing" depending on context.
• Why: This overlap is systematic across all four groups. Context, subject nouns, or pronouns clarify the meaning.

Usage Notes

Group I is by far the most common and is considered the "default" conjugation. When Romanian borrows verbs from other languages (English, French, etc.), they are almost always adapted as Group I verbs: a parca (to park), a scana (to scan), a downloada (to download).

Groups II and III are smaller and contain many commonly used verbs that tend to be irregular or semi-irregular. Group IV includes many everyday verbs related to bodily functions, cognition, and basic actions (a dormi — to sleep, a simți — to feel, a fugi — to run).

At the A1 level, focus on memorizing the most frequent verbs from each group rather than trying to master all four groups simultaneously. The patterns will become intuitive with practice and exposure.

Practice Tips

• Create a reference card with one model verb per group (a cânta, a vedea, a merge, a dormi) and their full conjugations. Review it daily until the patterns are automatic.
• When you learn a new verb, immediately identify its group by checking the infinitive ending. This habit prevents confusion later.
• Practice conjugating verbs aloud in all six persons. Speed drills — trying to say all six forms in under ten seconds — build the automaticity needed for conversation.
