'make annoyed' is the definition.
I can't judge whether this defines the answer.

'angry about unfinished ceremony' is the wordplay.
'angry' becomes 'irate' (irate can mean angry or annoyed).
'about' indicates putting letters inside.
'unfinished' means to remove the last letter.
'ceremony' becomes 'rite' (rite is a kind of ceremony).
'rite' with its final letter taken away is 'rit'.
'irate' enclosing 'rit' is 'IRRITATE'.

'and' is the link.
