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 definition defines the answer.
'sister accepting work needed with fiance?' is the wordplay.
'sister' becomes 'nun' (sister is a term of address for a nun).
'accepting' is an insertion indicator (inserted letters are accepted).
'work' becomes 'op' (short for opus).
'needed with' is a charade indicator (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".)
