Lesson 23: Imperfetto. Duration, habit, background in the past

Part 1: What imperfetto is

Imperfetto is Italian's second main past tense. It's the tense of duration, habit, background, and description.

Compare two views of the past:

Passato prossimo (L21–L22)	Imperfetto (this lesson)
point event, fact	process, ongoing
completed	no boundaries shown
"ate", "went", "bought"	"used to eat", "was going", "was buying"
Ieri ho mangiato la pasta.	Quando ero bambino, mangiavo la pasta ogni giorno.

Four main uses

1. Habit in the past — "I used to do, regularly". Quando ero piccolo, giocavo a calcio ogni sabato. — When I was little, I played football every Saturday.

2. Ongoing background action — "it was going on at that moment". Mentre leggevo, ha squillato il telefono. — While I was reading, the phone rang.

3. Description — setting, people, weather. Era una bella giornata. Il sole splendeva. Gli uccelli cantavano. — It was a beautiful day. The sun was shining. The birds were singing.

4. Age and time in the past. Avevo sei anni quando ho iniziato la scuola. — I was six when I started school. Erano le otto di sera. — It was eight in the evening.

The bridge for English speakers: imperfetto maps closely onto English "used to do" / "was doing" / "would (habitually) do". English Past Simple ("I played football") is ambiguous — it covers both "one time yesterday" and "every Saturday as a child". Italian splits these. Use passato prossimo for the one-time read, imperfetto for the habit/background read.

Key contrast for English speakers: the same English sentence "I played football" maps to TWO different Italian tenses:

• Ho giocato a calcio — passato prossimo (one time, yesterday)
• Giocavo a calcio — imperfetto (used to, as a kid) This is the same split Spanish makes with indefinido vs imperfecto. English Past Simple just hides it. You'll be re-training your habit of using one form for both.

Part 2: The form — regular endings

Imperfetto is one of the most regular forms in Italian. Take the verb stem and add endings.

Person	-are (parlare)	-ere (credere)	-ire (dormire)
io	parlavo	credevo	dormivo
tu	parlavi	credevi	dormivi
lui / lei	parlava	credeva	dormiva
noi	parlavamo	credevamo	dormivamo
voi	parlavate	credevate	dormivate
loro	parlavano	credevano	dormivano

Universal formula: each group has its own vowel — a / e / i — and the same tail: -vo, -vi, -va, -vamo, -vate, -vano. Lock in the tail, and the three conjugations assemble themselves.

Stress

In noi and voi, the stress falls on the third-to-last syllable: parlavamo, dormivate. In loro — also third from last: parlavano (NOT parlavano!).

Common error: the loro form is parlàvano, not parlavàno. Third from end is always the stem, not the ending.

Part 3: Irregular verbs — only four

Good news: imperfetto barely has any irregulars. Just memorize these.

essere → ero

Person	Form
io	ero
tu	eri
lui / lei	era
noi	eravamo
voi	eravate
loro	erano

fare → facevo (stem fac-, from old facere)

Person	Form
io	facevo
tu	facevi
lui / lei	faceva
noi	facevamo
voi	facevate
loro	facevano

bere → bevevo (stem bev-)

Person	Form
io	bevevo
tu	bevevi
lui / lei	beveva
noi	bevevamo
voi	bevevate
loro	bevevano

dire → dicevo (stem dic-)

Person	Form
io	dicevo
tu	dicevi
lui / lei	diceva
noi	dicevamo
voi	dicevate
loro	dicevano

The logic: fare, bere, dire all restore the "long" Latin stem (facere, bevere, dicere) that the infinitive hides. Memorize as "Latin root" if that helps. The same pattern applies to tradurre, condurre, produrre: traducevo, conducevo, producevo.

essere — pay close attention

Quando ero bambino… — When I was a child… Eravamo a Roma. — We were in Rome. C'era una volta… — Once upon a time… (classic story opening) C'erano molte persone. — There were many people.

"c'era / c'erano" is the imperfetto of c'è / ci sono. c'era for singular, c'erano for plural.

Part 4: The four uses with examples

Use 1: Habit / regular action in the past

Triggers: quando ero… / da bambino / sempre, spesso, di solito, ogni + day of week / ogni giorno, ogni anno.

Quando ero piccolo, andavo a scuola a piedi. — When I was little, I walked to school. Da bambino, leggevo molti libri. — As a child, I read a lot of books. Mio nonno fumava la pipa ogni sera. — My grandfather smoked a pipe every evening. Mia madre cucinava sempre la domenica. — My mother always cooked on Sundays.

English equivalents: "used to walk", "would read", "smoked every evening". All these English forms collapse to one Italian: imperfetto.

Use 2: Ongoing background action

Triggers: mentre / intanto / in quel momento / alle otto, alle dieci.

Mentre dormivo, è suonato il telefono. — While I was sleeping, the phone rang. Alle sette ero ancora in ufficio. — At seven I was still at the office. In quel momento studiavo il francese. — At that moment I was studying French.

English "was -ing" maps almost 1:1 onto imperfetto in this use.

Use 3: Description (people, nature, setting)

Era una notte fredda. Il vento soffiava forte. Le strade erano vuote. — It was a cold night. The wind was blowing hard. The streets were empty. Marco era alto, aveva i capelli neri e portava sempre gli occhiali. — Marco was tall, he had black hair, and he always wore glasses.

Use 4: Age and time in the past

Avevo dieci anni. — I was ten years old. Erano le tre del pomeriggio. — It was three in the afternoon. Era inverno. — It was winter.

Special rule: age in the past and time in the past always use imperfetto. Ho avuto dieci anni is meaningless. Always avevo dieci anni.
