Shouts of joy of one who's taking in work (6)
I believe the answer is:
whoops
'shouts of joy' is the definition.
'whoops' can be an answer for 'shouts' (whoop is a kind of shout). I'm not certain of the 'of joy' bit.
'one who's taking in work' is the wordplay.
'taking in' indicates putting letters inside.
'work' becomes 'op' (abbreviation for opus).
'whos' going around 'op' is 'WHOOPS'.
'of' is the link.
Can you help me to learn more?
(Other definitions for whoops that I've seen before include "Loud cries of excitement" , "Oh dear! That was a mistake!" , "Something said after minor accident or mistake" , "Worrying cry" , "Exclamation after a mistake; wild cries" .)
