Modal should

Advice and recommendation.

S + should + V1 (bare infinitive)

should is used for advice, recommendations, or expectations (what is sensible or right to do), without being a strict obligation. Like other modals, it takes the bare infinitive with no to.

Examples

  • You should check the rate before booking.
  • We should confirm the appointment window.
  • She should not sign without reviewing the terms.

  • You should to check.

    You should check.

    No to follows should: should check.

Common mistakes

  • Adding to after should: should to check → should check.
  • Treating should as a strict obligation when must/have to is actually meant.
