Common errors when using English modal verbs

The modal auxiliary verbs below use the structure "modal verb + infinitive" (without 'to')

can, could, may, might, must, shall, should, will, would

Examples:

  • When traveling, we should respect the customs of the countries we visit. (NOT should to respect; should respecting)
  • You must wear a helmet when cycling to protect your head in case of an accident. (NOT must to wear; must wearing)
  • Can you help me with this project? I believe your expertise would greatly benefit our team. (NOT can to help; can helping)
  • In emergency situations, you might need to act quickly to ensure everyone's safety. (NOT might to need; might needing)

Modal verb questions and negatives do not use the auxiliary verb "do":

  • May I join you? (NOT Do I may join you?)
  • Should we start now? (NOT Do we should start now?)
  • They couldn't come yesterday. (NOT They did not could come yesterday.)

When expressing obligation or necessity with "have" or "need", use "to + infinitive":

  • You have to submit your report by Friday.
  • She needs to decide soon.

In questions and negatives, "have to" and "need to" act as typical verbs, so we use "do":

  • Do I need to make a reservation in advance? (NOT need I to make …)
  • He mentioned I don't have to worry about parking. (NOT I haven't to worry …)
