Dynamic and Stative Verbs

Duration Expressions: For and Since

  • Core Function

    • For and since are used in conjunction with the present perfect to communicate the temporal duration of a situation that initiated in the past and persists into the present.

  • Usage of "For"

    • Denotes the entire span or quantity of time (how long an event has endured): for + a period of time.
    • Example: I've been living in this house for years.
    • Signal Words: 20 minutes, 2 hours, 3 days, a week, 6 months, 4 years, ages, a long time…

  • Usage of "Since"

    • Example: She's been singing with the school choir since 9 a.m.
    • Signal Words: 4.20 p.m., Monday, last week / month / year, January, 2011, I was a child…

  • Contrast with Italian Syntax

    • The present perfect combined with for and since translates directly into Italian using the presente indicativo accompanied by the preposition da:
    • English: I've been living here for twenty years, since 2004.
    • Italian: Vivo qui da 20 anni, dal 2004.

Present Perfect Simple vs. Present Perfect Continuous

    • Example: They've posted photos of that monument online several times.
    • Stative Verbs with Temporal Extent: Applied to stative verbs describing states that began in the past and continue into the present alongside for and since (reference Unit 1 Grammar reference, page 163).

  • Present Perfect Continuous Applications

    • Uninterrupted Actions: Applied to underline the persistent, continuous quality of an action that has proceeded without breaks.
