> Bare infinitive grammar, definition, usage, and examples — understanding the base form of a verb without "to" in English.
The bare infinitive is the base form of a verb without the particle to (e.g., go, see, make). It is a simple, unmarked form used in specific grammatical constructions.
  • Bare infinitive = base verb form without "to"
  • Example: She goes vs. She go (bare infinitive)
  • Used after certain verbs, modals, and expressions in English

Building the Overview Section

The bare infinitive appears in several key contexts:
  • After modal verbs (can, will, must, etc.)
  • After certain verbs like let, make, see, hear
  • Following "why" in questions without auxiliary verbs
  • After "had better," "would rather," and "sooner"

Building the Detailed Explanation Section

1. Verbs That Require a Bare Infinitive

Certain verbs are followed directly by a bare infinitive (never "to" + verb):
  • let (Let me go.)
  • make (She made him apologize.)
  • see (I saw her leave.)
  • hear (We heard them sing.)
  • feel (He felt the ground shake.)

2. Modal Verbs

All modal verbs are followed by a bare infinitive:
  • can, could, may, might, will, would, shall, should, must, etc.
  • Example: She can sing. / You must go.

3. Special Expressions

The bare infinitive is used after certain fixed expressions:
  • had better (You had better leave.)
  • would rather (I would rather stay.)
  • sooner (I’d sooner walk than drive.)

4. Question Words (Why)

When “why” introduces a question without an auxiliary, use the bare infinitive:
  • Why wait?
  • Why go now?
