The Class III overview tells you the present endings are regular but the stems are full of quirks, and that the class hoards irregulars. True — and that is exactly why a flat alphabetical list of Class III verbs is the wrong way to learn them. This page gives you the organizing trick experienced learners use: subgroup the class along two axes — by the stem-final consonant (which governs the present-tense alternations) and by the participle type (-s, -t, or -ut), which turns out to predict a verb's whole irregular profile. Once a verb is filed into a subgroup, its forms stop feeling like surprises.
Two axes, not one rule
Class III resists a single generative rule because it inherited verbs from several Latin patterns at once. So instead of one rule, use two classifications:
- Stem-final consonant — -g (a merge), -c (a face, a zice, a duce), -t (a bate), -d (a crede), -p (a rupe), -n (a spune), -s (a coase). This determines what happens before the tu -i.
- Participle type — does the past participle end in -s (mers), -t (rupt), or -ut (bătut)? This sorts the class into three behavioral families and predicts a verb's compound tenses.
The present endings themselves are constant: — / -i / -e / -em / -eți / — (or -u), with eu = ei/ele (bare stem) and stress always on the stem (MER-gem, never mer-GEM).
Axis 1: stem-final consonant and the tu form
The tu -i is where Class III stems do their visible work. The front vowel reshapes the final consonant — the same sound laws that drive noun plurals (see stem alternations).
| Stem ends in | Verb | eu | tu | Change before -i |
|---|---|---|---|---|
| -g | a merge (go) | merg | mergi | g softens (gh → soft g) |
| -c | a face (do/make) | fac | faci | c softens (k → soft c) |
| -c | a zice (say) | zic | zici | c softens |
| -c | a duce (carry) | duc | duci | c softens |
| -t | a bate (hit) | bat | bați | t → ț |
| -d | a crede (believe) | cred | crezi | d → z |
| -p | a rupe (tear) | rup | rupi | p — no change |
| -n | a spune (say/tell) | spun | spui | n drops before -i |
Two surprises in that table. The -c and -g verbs (face, zice, duce, merge) soften their final consonant in sound before -i even though the spelling keeps the c/g — faci is "fatch," zici is "zitch," mergi has a soft g (see soft vs hard c/g). And a spune loses its -n before the tu -i: spun → spui, not spuni.
Faci tu cafeaua sau o fac eu?
Are you making the coffee or shall I?
Ce zici, mergem sau mai stăm?
What do you say — shall we go or stay a bit longer?
Tu spui mereu adevărul, asta apreciez la tine.
You always tell the truth, that's what I value in you. (spui — n drops)
The core -c paradigms: a face, a zice, a duce
These three are the most frequent Class III verbs and share a shape: hard -c stem softening before the tu -i, regular endings, stress on the stem. They are tame in the present; their irregularity erupts in the participle (next section).
| Person | a face | a zice | a duce |
|---|---|---|---|
| eu | fac | zic | duc |
| tu | faci | zici | duci |
| el / ea | face | zice | duce |
| noi | facem | zicem | ducem |
| voi | faceți | ziceți | duceți |
| ei / ele | fac | zic | duc |

Axis 2: participle type, the real predictor
Here is the insight that pays off most. Romanian Class III verbs sort cleanly into three families by how the past participle ends — and the participle ending is the best single predictor of a verb's irregular forms (perfect compus, past participle as adjective, supine). Grouping by it turns a chaotic class into three tidy bins.
| Participle | Verb | eu (present) | Participle | "I have ..." (perfect) |
|---|---|---|---|---|
| -s | a merge (go) | merg | mers | am mers |
| -s | a zice (say) | zic | zis | am zis |
| -s | a duce (carry) | duc | dus | am dus |
| -s | a spune (tell) | spun | spus | am spus |
| -t | a rupe (tear) | rup | rupt | am rupt |
| -t | a coace (bake) | coc | copt | am copt |
| -t | a frige (fry/roast) | frig | fript | am fript |
| -ut | a bate (hit) | bat | bătut | am bătut |
| -ut | a crede (believe) | cred | crezut | am crezut |
| -ut | a face (do/make) | fac | făcut | am făcut |
Notice the families behave consistently. The -s group (mers, zis, dus, spus) tends to compress the stem hard in the participle. The -t group (rupt, copt, fript) is small but recognizably similar (coace/frige even diphthongize their stem in the present: coc → coace, frig → frige). The -ut group (bătut, crezut, făcut) is the most regular-looking and the largest. Knowing which bin a verb sits in tells you its perfect, its passive participle, and its supine all at once.
Am mers pe jos până acasă, era o seară frumoasă.
I walked all the way home, it was a lovely evening. (a merge, -s participle)
Mi-am rupt cureaua de la ceas.
I broke my watch strap. (a rupe, -t participle)
N-am crezut o vorbă din ce mi-a spus.
I didn't believe a word of what he told me. (a crede, -ut participle)
Stem diphthongization in some Class III verbs
A subset of Class III verbs diphthongize the stem under third-person stress, just like Class I and IV. The most useful are a coace (to bake) and a frige (to fry/roast), plus a scoate (to take out).
| Infinitive | eu / ei | tu | el / ea | noi |
|---|---|---|---|---|
| a coace (bake) | coc | coci | coace | coacem |
| a scoate (take out) | scot | scoți | scoate | scoatem |
| a frige (fry) | frig | frigi | frige | frigem |
So eu scot but el scoate; eu coc but el coace. The o→oa diphthong appears wherever the stressed stem precedes the -e (3sg) or carries through the stem (scoatem).
Scot pâinea din cuptor în cinci minute.
I'll take the bread out of the oven in five minutes.
Mama coace cozonac de fiecare Crăciun.
Mom bakes cozonac every Christmas.
Don't overgeneralize one subtype's endings
The single biggest Class III error is taking one subtype's quirk and spraying it across the class. The participles are family-bound: don't assume a merge's -s participle means a bate has one (bate → bătut, not *bas), and don't assume a rupe's -t participle means a crede has one (crede → crezut, not *crept). The same goes for present-tense alternations: a scoate diphthongizes (scot/scoate), but its neighbor a bate does not (bat/bate, no diphthong). Each subgroup is internally consistent, but you must not export a subgroup's behavior to the others — file the verb correctly first, then apply only that subgroup's rules.
Common Mistakes
❌ Tu spuni mereu adevărul.
Incorrect — a spune drops its -n before -i: spui.
✅ Tu spui mereu adevărul.
You always tell the truth.
❌ Tu credi în noroc?
Incorrect — d palatalizes to z before -i: crezi.
✅ Tu crezi în noroc?
Do you believe in luck?
❌ Am mert pe jos până acasă.
Incorrect — a merge takes an -s participle: mers, not *mert.
✅ Am mers pe jos până acasă.
I walked all the way home.
❌ El scote pâinea din cuptor.
Incorrect — the 3sg of a scoate diphthongizes: scoate (o → oa).
✅ El scoate pâinea din cuptor.
He takes the bread out of the oven.
❌ Noi merGEM la teatru.
Incorrect stress — Class III is stem-stressed: MERgem.
✅ Noi MERgem la teatru.
We're going to the theater.
Key Takeaways
- Tame Class III by subgrouping, not by a single rule.
- Axis 1 — stem-final consonant predicts the tu form: g/c soften (mergi, faci, zici), t→ț (bați), d→z (crezi), n drops (spui).
- Axis 2 — participle type (-s: mers; -t: rupt; -ut: bătut) predicts a verb's whole irregular profile, including the compound past.
- Learn each verb as a present-eu + participle pair (merg/mers, rup/rupt, bat/bătut).
- A subset diphthongizes the stem (scot/scoate, coc/coace) under 3rd-person stress.
- Don't export one subtype's quirk to the others; each subgroup is consistent only within itself.
