The Pretérito imperfeito

📌 Nota gramatical

The pretérito imperfeito do indicativo is used to describe ongoing, habitual, or repeated actions in the past, as well as background descriptions, time, weather, and age. Unlike the preterito perfeito, it does not focus on the beginning or end of an action, but rather on its duration or frequency.

📌 Nota gramatical

To conjugate regular -AR verbs (like falar, cantar, morar) in the imperfect, drop the -AR ending and add the following endings: -ava, -avas, -ava, -ávamos, -áveis, -avam. Note the written accent on the first-person plural (-ávamos).

📌 Nota gramatical

Regular -ER and -IR verbs (like comer, beber, partir, sorrir) share the exact same set of imperfect endings: -ia, -ias, -ia, -íamos, -íeis, -iam. Always include the accent on the 'i' in all plural forms (-íamos, -íeis, -iam has accent on 'i' in -íeis, but -iam does not; wait, -íamos, -íeis).

📌 Nota gramatical

The verb 'ser' is highly irregular in the imperfect tense. Its stem changes completely to 'era'. The full paradigm is: eu era, tu eras, ele/ela/você era, nós éramos, vós éreis, eles/elas/vocês eram. It is essential for describing past identities, traits, and permanent states.

📌 Nota gramatical

Unlike the present tense where 'ter' has stem changes (tenho, tens), in the imperfect tense, 'ter' is completely regular based on its -ER ending: eu tinha, tu tinhas, ele/ela/você tinha, nós tínhamos, vós tínheis, eles/elas/vocês tinham. Note the accent on the 'i' in the plural forms.

📌 Nota gramatical

The verb 'vir' takes the stem 'vin-' in the imperfect tense, following the regular -IR endings. Paradigm: eu vinhas (no, eu vinha), tu vinhas, ele vinha, nós vínhamos, vós vínheis, eles vinham. Note the accents on vínhamos and vínheis.

📌 Nota gramatical

The verb 'pôr' (historically poer) derives its imperfect from its old stem 'pun-'. Therefore, it conjugates as: eu punha, tu punhas, ele punha, nós púnhamos, vós púnheis, eles punham. It follows the -ER ending pattern after the 'pun-' base.

📌 Nota gramatical

When telling a story in the past, use the imperfect tense for descriptions (weather, time, physical appearance, emotional state, age). These elements form the backdrop against which specific, completed events (preterito perfeito) happen.

📌 Nota gramatical

The imperfect is the primary tense to express frequency and habitual actions in the past (equivalent to English 'used to' or 'would'). Common time markers include 'antigamente' (formerly), 'todos os dias' (every day), 'sempre' (always), and 'muitas vezes' (often).

📌 Nota gramatical

When two or more continuous actions occur simultaneously in the past, both verbs take the imperfect tense, often connected by the conjunction 'enquanto' (while).

📌 Nota gramatical

A very common narrative pattern uses the imperfect tense to describe an ongoing background action, which is then interrupted by a sudden, completed action in the preterito perfeito. The word 'quando' (when) frequently links the two clauses.

📌 Nota gramatical

In conversational European Portuguese, the imperfect tense of verbs like 'querer', 'poder', or 'gostar' can be used to make polite requests, express modest desires, or soften statements, making them sound less abrupt.
