Labor or Labour | Definition, Spelling & Examples

Labor and labour are different spellings of the noun meaning ‘work’, ‘a group of manual workers’, and ‘the process of giving birth’ and the verb meaning ‘work hard’ and ‘discuss something at unnecessary length’.

The spelling varies depending on whether you’re using UK or US English:

  • In US English, ‘labor’ (no ‘u’) is standard.
  • In UK English, ‘labour’ (with a ‘u’) is the correct spelling.
    Examples: Labor and labour in a sentence
    The prisoner was sentenced to hard labor/labour.

    The woman was in labor/labour for a full day before her child was born.

    The workers labored/laboured to repair the damaged bridge.

    You don’t need to labor/labour the point! I know I was wrong.

    Note
    Many words that end in ‘-our’ in UK English end in ‘-or’ in US English. Some other common examples include ‘behaviour/behavior‘, ‘colour/color‘, ‘favour/favor‘, and ‘honour/honor‘.

        Exception: Laborious

        While ‘labour’ is the standard spelling in UK English, the related adjective laborious (meaning ‘tedious’) is used in both US and UK English. This is also the case for the adverb laboriously. Spelling these words with ‘-our-‘ is never correct.

            Example: Laborious in a sentence
            The principal gave a laborious speech on graduation day.

            Exception: Labour as a proper noun

            In the UK, ‘Labour’ is used as a proper noun to refer to the UK Labour Party.

                Example: Labour as a proper noun
                Michael is going to vote for Labour in the upcoming election.
