In this post, we’ll look at modal verbs and will analyze examples to help you build your confidence in using them for your test day.

A look at modal verbs

Modal verbs are a small group of verbs that express the speaker’s attitude towards or opinion about what is being said. Modal verbs include the following:

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

Modals are different from normal verbs like play or study in that they never change form and are always followed by an infinitive without ‘to’ (e.g. can do, would work, should go, etc.). We use them to show how certain we are about what we’re saying, or to talk about ability, obligation, give advice, ask permission, and make requests and offers. For example, the modal verb must can express a speaker’s sense of obligation (e.g. We must help protect the environment.), and how probable a speaker thinks something is (e.g. Working 12-hour shifts must be exhausting.)

Because modal verbs have various uses and irregular negative and past forms (e.g. He can’t complete the project on his own. (present) vs. He couldn’t/wasn’t able to complete the project on his own. (past)) they can be tricky to master. However, exploring examples of modal verbs in use can help you to better understand this complex area of English grammar.

Examples of modal verbs

Here’s a list of modal verbs with examples that you may find particularly useful on your IELTS:

Modal verbs in hedging

Hedges are an important part of polite conversation and academic writing, and you may find hedging to be very useful on your IELTS. You can use hedges to soften what you say or write, as they help to make your statements a little less direct. You can also use hedging to express that you’re not completely certain of what you’re saying. One of the most common forms of hedging involves using modal verbs:

  • The answer c ould be that…
  • It may be that…
  • Such a measure might be…
