Sister accepting work needed with fiancé? It’s not really funny (2,3,8)
I believe the answer is:
no pun intended
'not really funny' is the definition.
I can't tell whether this defines the answer.
'sister accepting work needed with fiance?' is the wordplay.
'sister' becomes 'nun' (nuns are referred to as sister).
'accepting' means one lot of letters goes inside another (inserted letters are accepted).
'work' becomes 'op' (abbreviation for opus).
'needed with' says to put letters next to each other (some letters need to go next to others).
'fiance?' becomes 'intended' (someone's intended is their fiance).
'nun' placed around 'op' is 'nopun'.
'nopun'+'intended'='NO PUN INTENDED'
'it's' is the link.
Can you help me to learn more?
(Another definition for no pun intended that I've seen is " That's no joke".)
