Confusing Words

aloud vs allowed

These two words sound exactly the same but have very different meanings.

  • aloud — Aloud' is an adverb meaning out loud or in a voice that others can hear — for example, She read the poem aloud to the class so everyone could appreciate the rhythm and rhyme.
  • allowed — Allowed' is the past tense of the verb 'to allow', meaning to have permission to do something — for example, Students are not allowed to use their devices during the assessment.

Memory rule: A helpful trick: 'aloud' contains 'loud', which reminds you that it is about sound and speaking. If you mean 'having permission', use 'allowed'.
