The imperfect: action in progress

The imperfect: action in progress

The imperfect adds -bā- in the first two conjugations: ambulābat can mean “was walking” or “used to walk.” It gives background, duration, and repeated past action rather than viewing an event as a completed whole.

The imperfect presents a past action from inside

Tense locates an action in time, while aspect describes how the speaker presents it. The imperfect is past and imperfective: it can show action in progress, repeated action, an attempted action, or a state that formed the background. English may use ‘was walking,’ ‘used to walk,’ or a simple past according to context.

In the first and second conjugations, -bā- is the visible imperfect marker before the personal ending: amābam, amābās, amābat; monēbam, monēbās, monēbat. sum is irregular: eram, erās, erat, erāmus, erātis, erant. Keep person and number distinct from tense: -bā- places the scene in past time, while -t or -nt identifies its subject.

Let adverbs and a second verb establish the scene

Puella saepe ad templum ambulābat means ‘The girl often used to walk to the temple.’ saepe encourages a habitual reading. Puella ad templum ambulābat tum amīcum vīdit means ‘The girl was walking toward the temple when she saw a friend.’ The imperfect supplies the ongoing frame; the perfect vīdit supplies a completed event within it.

Not every imperfect must be translated with ‘was.’ Rōma magna erat is naturally ‘Rome was large,’ while puer aquam portābat might be ‘the boy was carrying water’ or ‘used to carry water.’ Choose English after identifying the form and reading the larger narrative relationship.

See the past in progress

For first- and second-conjugation verbs, the marker -bā- appears before the personal ending: ambulābat, ‘was walking’ or ‘used to walk.’ erat is the imperfect of sum. The imperfect does not simply mean ‘past’; it presents an action from inside its duration or repetition.
