Bare Infinitive Usage in English

Sep 1, 2025

Overview

This lecture explains the bare infinitive, its usage, and how it differs from the full infinitive form with "to" in English grammar.

Infinitive vs. Bare Infinitive

  • The infinitive is the base verb with "to" (e.g., to play).
  • The bare infinitive is the base verb without "to" (e.g., play).
  • "To" infinitives are usually used after certain verbs like "want" or "like".
  • Bare infinitives are used after certain words and expressions, mainly modal and auxiliary verbs.

Usage of Bare Infinitives

  • Bare infinitives follow modal verbs: can, could, may, might, should, would, will, shall, must.
  • Examples: "He can play," "He should go," "He will win."
  • Used after auxiliary verbs do, does, did to form questions and negatives (e.g., "Did he eat?" "He does not play.").
  • Used after verbs of perception: see, hear, feel, watch, notice, smell (e.g., "I saw him leave").
  • Used after make, have, and let (e.g., "Let him eat," "She made me cry").
  • Used after expressions: would rather, cannot but, dare not, need not (e.g., "I would rather stay," "You need not worry").
  • Sometimes used after "why" for making suggestions (e.g., "Why wait?").
