A group penning paper linked to data transmission? I’ll need time to get it (8,5)
I believe the answer is:
acquired taste
'i'll need time to get it' is the definition.
(it takes time to develop an acquired taste)
'a group penning paper linked to data transmission?' is the wordplay.
I cannot really understand how this works, but
'a' is within the answer.
'paper' could be 'quire' (paper measurement) and 'quire' is present in the answer.
'data transmission?' could be 'dt' (abbreviation) and 'dt' is found within the answer.
'group' could be 'caste' (an ethnic or social group) and 'caste' is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
(Other definitions for acquired taste that I've seen before include "Item not immediately appreciated" , "Something one grows to like" , "It's something you may come to like" , "Something one can grow to like" , "Something one comes to like" .)
