Irregular Present Verbs: Consolidated Reference

Romanian's genuinely irregular present verbs are few — you can count them on two hands — but they are among the most frequent words in the language, so they are the verbs you will say and hear constantly. This is no coincidence: a verb stays irregular precisely because it is used so often. Constant repetition shields it from the "leveling" pressure that smooths rare verbs into a regular class. To be, to have, to want, to give, to take — the most-used verbs in any language tend to be the most irregular, in Romanian as in English. This page is the consolidated lookup: every truly irregular present paradigm gathered in one place, so you can compare them, drill them, and find them fast. Each verb also has its own dedicated page (linked) for the deeper treatment; this is the reference you keep open.

What counts as "irregular" here

A verb is irregular in the present when you cannot derive its full paradigm from a class rule plus a known stem change. By that test, the irregulars are: a fi (to be), a avea (to have), a vrea (to want), a da (to give), a sta (to stay), a lua (to take), a bea (to drink), and a ști (to know). Note what is not here: predictable stem-changers like a pleca (pleacă) or a dormi (doarme) are regular once you apply the stem-change rules; and verbs like a usca (to dry: usuc, usuci, usucă) only look odd because of routine c-softening. Those follow rules. The eight below do not.

The two essential auxiliaries: a fi and a avea

Learn these two first and overlearn them — beyond their own meanings, they build the passive (a fi) and the entire compound past (a avea). Full treatment on the a fi and a avea pages.

A fi is suppletive — sunt, ești, este come from unrelated roots, exactly like English am/is/be. A avea has short irregular singulars (am, ai, are) and an av- stem in the plural; its 3sg (are) and 3pl (au) happen to differ, a small mercy.

a vrea (to want) and its future-auxiliary twin

A vrea leads a double life: the "want" verb, and — in a worn-down form — the literary future auxiliary. See the a vrea page for the full split.

The form vor belongs to both paradigms ("they want" / "they will"); what follows disambiguates — a noun or să-clause means "want," a bare infinitive means "will." And remember the structural rule: "want to do" is vreau *să plec*, never an infinitive.

The monosyllabic vowel-stem irregulars: a da, a sta, a lua, a bea

These four short verbs end their stems in a vowel, which collides with vowel-initial endings to produce contractions and diphthongs no rule reconstructs. They are covered in depth on the a da / a sta page. The headline trait: the eu form and the ei/ele form are identical in all four (dau, stau, iau, beau).

A da and a sta are twins — st- simply replaces d- throughout, so learn them as a pair. A lua is the trickiest paradigm in the language because it uses two stems: the strong ia- in the singular and 3pl (iau, iei, ia, iau) and the weak lu- only in noi/voi (luăm, luați). A bea keeps a vowel-final be- stem with the -au diphthong only in eu/ei.

a ști (to know a fact)

An old, short irregular built on a ști- stem. The only thing to watch is the tu form știi, with a doubled i (stem i + ending -i). Full treatment, plus the a ști / a cunoaște split, on the a ști page.

The patterns that tie the irregulars together

Even irregular verbs are not pure chaos. Three recurring traits run through this set, and noticing them lightens the memory load:

1. The 1sg = 3pl trap. Look how many of these collapse "I" and "they" into one form: sunt (a fi), dau / stau / iau / beau (the vowel-stem four), știu (a ști), and even vor indirectly. Romanian leans on the subject (pronoun or noun) or context to tell them apart — keep the pronoun when ambiguity looms.

2. The vowel-final stem diphthongizes the edges. Dau, stau, iau, beau all end the 1sg/3pl in the -au diphthong because the stem ends in a vowel that merges with the ending. This is the same phonetic pressure, just applied to verbs too short to absorb it gracefully.

3. They double as grammatical machinery. A fi builds the passive; a avea builds the compound past; a vrea builds the literary future. The three most irregular verbs are also the three load-bearing auxiliaries — which is exactly why they were used often enough to stay irregular.

How this set compares to English

English has its own tiny club of high-frequency irregulars — be, have, do, go, take, give — and for the same reason: heavy use preserves old forms. So the concept is familiar; an English speaker already accepts that to be is am/are/is with no derivable logic. The trap is assuming Romanian's irregulars overlap with English's. They mostly don't: a da and a sta are wildly irregular in Romanian but their English counterparts (give, stay) are regular, while English do (irregular) maps to a face, which is regular in the Romanian present. So accept the irregular concept from English, but learn which Romanian verbs are irregular from scratch — the lists do not match.

Common Mistakes

Key Takeaways

• The truly irregular present verbs are eight: a fi, a avea, a vrea, a da, a sta, a lua, a bea, a ști — memorize them as whole paradigms.
• They are irregular because they are frequent; high use shields them from leveling.
• A recurring trap is 1sg = 3pl (sunt, dau, stau, iau, beau, știu) — disambiguate with the subject.
• A da/a sta are twins; a lua uses two stems (ia- / lu-); a bea keeps a be- stem with -au edges.
• The three most irregular (a fi, a avea, a vrea) double as the passive, compound-past, and future auxiliaries.
• English has the same concept of frequent irregulars, but the lists don't match — learn the Romanian set fresh.
