Root Explanation

**Adjoint** → The word 'adjoint' comes from the Old French 'adjoint', which means 'joined to' or 'added'. It is formed from 'ad-' (meaning to) and 'junctus' (meaning joined). The term refers to something that is added or joined to another thing, particularly in mathematical contexts.

Memory Tip

Think of something that is 'added to' another — 'ad-' means to, and 'junctus' means joined. This helps you remember that 'adjoint' refers to something that is joined or added.
