Loosely hang fish at end of day (6)
I believe the answer is:
dangle
'loosely hang' is the definition.
'dangle' can be an answer for 'hang' (dangling is a kind of hanging). I am unsure of the 'loosely' bit.
'fish at end of day' is the wordplay.
'fish' becomes 'angle' (synonyms).
'at end of' says to put letters next to each other (some letters go at the end of others).
'day' becomes 'd' (abbreviation for day).
'angle' after 'd' is 'DANGLE'.
Can you help me to learn more?
(Other definitions for dangle that I've seen before include "Hang provocatively" , "Hang -- Glenda (anag)" , "wave" , "Hang loosely or swing" , "Hang so as to swing freely" .)
