Cominciare: Full Conjugation

Cominciare (to begin, to start) is one of the first verbs every learner of Italian meets, and it carries two grammar lessons that come back again and again. First, it belongs to the -ciare family — verbs whose stem ends in a soft ci /tʃ/ sound — which means it follows the i-drop spelling rule: the silent i of the stem is dropped before any ending that already starts with i or e. So the tu form is cominci, not cominicii; the future is comincerò, not comincierò. Second, it shows the transitive vs intransitive auxiliary split: when you start something (a transitive object), the auxiliary is avere (ho cominciato il libro); when something starts on its own (intransitive), the auxiliary is essere (è cominciata la pioggia). Both lessons land in week one of A1 and pay dividends across the entire verb system.

Etymologically, cominciare comes from Vulgar Latin *cominitiare, a compound of cum- (with, together) and initiare (to initiate), itself from initium (beginning). The same Latin root gave Italian its more learned synonym iniziare — used interchangeably with cominciare in most contexts, with iniziare sounding marginally more formal and a touch more "purposeful initiation" than the everyday "get going" feel of cominciare. The antonym across all uses is finire (to finish).

Indicativo presente

Walk through the i-drop logic carefully, because exactly the same mechanic recurs in mangiare, baciare, lasciare, viaggiare, abbracciare and dozens more. The infinitive ends in -ciare, where the i is purely orthographic — a silent marker that tells you the c is soft (/tʃ/, like English "ch" in church), not hard (/k/). When the ending already starts with i or e, the c will be soft anyway, so the silent i is redundant and drops. Hence:

• tu cominci — single i (the ending -i already softens the c)
• noi cominciamo — i kept, because the ending -iamo starts with i and the cluster cia- preserves the soft sound across the syllable break

Note carefully that the noi form keeps the i because the i there is part of the syllable -cia- that opens -iamo. Do not write cominciamo as cominicia­mo (a hyper-corrected double-i form) or as comin-ciamo with the i dropped (which would harden the c incorrectly).

The stress in the loro form is comìnciano — first syllable of the stem (well, second of the word: co-MIN-cia-no), not the ending. As with all -are verbs, the stress in 1sg, 2sg, 3sg, and 3pl falls on the root; in 1pl and 2pl it shifts to the ending. See presente: regular -are verbs for the full pattern.

Imperfetto

Fully regular -are imperfetto on the stem cominc-, with the i retained throughout because the imperfetto endings all start with -a- (the soft c needs the i to stay soft). No spelling complications here.

Passato remoto

Regular passato remoto. Note three things: the stem-final i is kept throughout because every ending starts with -a- (the soft c needs the i to stay soft); the mandatory grave accent on the 3sg cominciò — never write comincio for "he/she began" (that's the present tense); the double m in 1pl cominciammo (distinguishing the historical past from the present cominciamo).

The verb is heavily used in literary and biographical narrative, where the passato remoto is the dominant past tense: La sua carriera cominciò nel 1978 — "Her career began in 1978."

Futuro semplice

This is the form where the i-drop rule visibly bites. The future stem of an -are verb is normally built by replacing the -are ending with -erò, -erai, -erà, -eremo, -erete, -eranno. Apply that to cominciare and you would get cominci-erò — but the silent i of the stem is now redundant, because the ending -erò already starts with e (which keeps the c soft on its own). So the i drops, giving comincerò /ko-min-tʃe-RO/.

Mandatory grave accents on comincerò (1sg) and comincerà (3sg) — these mark the stressed final vowel.

Condizionale presente

Same i-drop in the conditional — comincerei, never comincierei. The standard -are conditional endings, with the famous double-m in cominceremmo (conditional, "we would start") versus single-m cominceremo (future, "we will start"). This single/double-m contrast is the most-tested spelling distinction in Italian writing.

Congiuntivo presente

The three singulars collapse into cominci — identical to the 2sg of the indicativo presente. Subject pronouns disambiguate when needed, but in practice context resolves it almost always (spero che cominci a piovere, bisogna che tu cominci subito).

The 3pl comincino drops the i of the stem because the ending -ino itself starts with i (which softens the c on its own).

Congiuntivo imperfetto

Standard -are congiuntivo imperfetto on the stem cominc-, with the i kept throughout because every ending starts with -a-. Used heavily in counterfactuals: se cominciassi adesso, finirei domani ("if I started now, I'd finish tomorrow").

Imperativo

The tu imperative is identical to the 3sg of the present indicative: comincia! ("start!"). The formal Lei imperative is cominci! — borrowing the form from the congiuntivo presente. Both are heard daily: a teacher might say Comincia tu, Marco to a student, or Cominci pure, dottore to a senior colleague.

A useful set phrase: Cominciamo bene! — said sarcastically when something has already gone wrong at the very beginning ("we're off to a great start").

Forme non finite

The participle cominciato is regular and agrees with the subject when the auxiliary is essere (the intransitive sense). It also functions as a free-standing adjective: un lavoro appena cominciato ("a just-begun job"), un'opera mai cominciata ("an opera never begun").

The auxiliary split: avere or essere?

This is the second big lesson of cominciare, and the rule is exact:

• Transitive use (cominciare something) → auxiliary avere, no agreement.
• Intransitive use (something cominciare on its own) → auxiliary essere, participle agrees with the subject.

The clue is whether there is a direct object after the verb. If you started a book, the meeting, your career, that's transitive — use avere. If the meeting, the rain, the film started by itself with no agent, that's intransitive — use essere.

Compound tenses

The participle cominciato combines with both auxiliaries depending on transitivity. Below is the full table for the most common compound tenses, in the transitive (avere) form. For the intransitive sense, swap avere → essere and add agreement (è cominciata, sono cominciati, sono cominciate).

Cominciare a + infinitive: the construction you'll use most

By far the most frequent pattern with cominciare in everyday speech is cominciare a + infinitive ("to start doing X"). The preposition is fixed: it is always a, never di or per. The same construction is shared with iniziare (its synonym), with mettersi a (to set about doing), and with stare per (which means the related "to be about to do").

Synonyms and antonym

• iniziare — same meaning, marginally more formal/written register, slightly more "purposeful initiation." Conjugation parallels cominciare exactly, with the same i-drop rule (inizio, inizi, inizia, iniziamo, iniziate, iniziano; futuro inizierò — note that inizierò keeps the i in writing because the i of inizi- is part of the stem rather than a soft-consonant marker; this is a rare convention split worth noticing).
• mettersi a + infinitive — "to set about, to start doing" with a sense of effort or commitment.
• avviare — to set in motion, to start (a project, a business). More managerial.
• partire — used colloquially for "to start" of events: il film parte alle nove.
• finire — antonym, "to finish." Pairs with cominciare in countless idioms: Hai cominciato tu, finiscila tu ("You started this, you finish it").

Set phrases worth memorising

• per cominciare — "to begin with, for starters." Common discourse marker.
• cominciare da capo — to start over from the beginning.
• cominciare male / bene — to start off badly / well.
• chi ben comincia è a metà dell'opera — "well begun is half done" (proverb, very widely cited).
• tanto per cominciare — "just to start (the list of complaints)."
• cominciare con il piede sbagliato / giusto — to start off on the wrong / right foot.

Common mistakes

Key takeaways

Cominciare is a textbook regular -are verb with two memorable wrinkles:

1. The i-drop rule. The silent i of the stem disappears before any ending starting with i or e. So tu cominci (one i), future comincerò (no i before -erò), conditional comincerei — but noi cominciamo keeps the i because the ending starts with -iamo, where the i is the syllable-opener of -iamo. The same rule applies to the entire -ciare and -giare family: see mangiare, and the c/g orthographic rule for the underlying logic.

2. The auxiliary split. Avere when transitive (ho cominciato il libro), essere when intransitive (è cominciato il film). The participle agrees with the subject only when essere is the auxiliary. This split applies equally to finire, iniziare, terminare, continuare — once you learn it for one, you have it for all.

3. The construction is cominciare a + infinitive — never di, never per. Drill cominciare a leggere, cominciare a piovere, cominciare a capire as fixed units.

4. Watch the spelling traps in writing: comincerò (not comincierò), cominceremo vs cominceremmo (single-m future, double-m conditional), cominciò (not comincio for "he/she began").

The mandatory companion is mangiare, which shares the i-drop rule with a -giare stem instead of -ciare. Master the pair and you have the spelling logic for half the high-frequency -are vocabulary.
