The form -eur is a suffix that marks an agent noun or, occasionally, an adjective in loanwords from French. Agent nouns are nouns that indicate a person who does an action. Broadly speaking, then, -eur means “doer.” The suffix -eur is relatively common in both everyday and technical terms.

The suffix -eur ultimately comes from the Latin -or or -ator, which was used to indicate agent nouns.

An equivalent of -eur in words from English is the suffix -er, as in singer (someone who sings).

What are variants of -eur?

When agent nouns ending in -eur are used to refer to a feminine-gendered element, -eur becomes -euse, as in chanteuse (a female singer). Although -eur is a masculine-gendered ending for agent nouns, it is often (though not always) preferred over -euse as the default in English, regardless of the subject’s gender.
