Relating to or serving to connect or couple things together, especially in grammar where it links a subject to its complement.
From Latin 'copulativus,' derived from 'copulare' (to couple). In linguistics, it describes verbs that join rather than show action.
The verb 'is' is the ultimate copulative verb—it's not an action but a connector, which is why 'She is happy' works so differently from 'She runs happily.'
