Gerunds vs. Infinitives

Gerunds and infinitives can both function as nouns, but they are used in different contexts following certain verbs or prepositions.

Gerund (V-ing as a noun)

  • Used after prepositions:
    • Example: good at swimming
  • Used after certain verbs:
    • enjoy, avoid, consider, deny, mind, suggest, finish, keep, practice, risk, admit, imagine, postpone, regret

Infinitive (to + V1)

  • Used after certain verbs:
    • want, wish, hope, plan, decide, refuse, agree, manage, offer, promise, seem, appear, afford, learn, pretend, threaten

Both Possible (with meaning change)

Some verbs can be followed by either a gerund or an infinitive, but the meaning changes:

  • remember doing (past action) vs. remember to do (future task)
  • stop doing (cease an activity) vs. stop to do (pause in order to do something else)
  • try doing (experiment with an action) vs. try to do (attempt to achieve something difficult)
Correct Example
  • I enjoy swimming. (Gerund after 'enjoy')
  • She decided to leave. (Infinitive after 'decide')
  • He remembered locking the door. (Past action)
Incorrect Example
  • I enjoy to swim. ('Enjoy' typically takes a gerund)
  • She decided leaving. ('Decide' typically takes an infinitive)
