Acidic measure in US cell? (5)
I believe the answer is:
phone
'us cell?' is the definition.
'phone' can be an answer for 'cell?' (I've seen this in another clue). I'm unsure of the 'us' bit.
'acidic measure in' is the wordplay.
'acidic' becomes 'phoe' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'measure' becomes 'N' (N is an example).
'in' is an insertion indicator.
'phoe' going around 'n' is 'PHONE'.
Can you help me to learn more?
(Other definitions for phone that I've seen before include "Receiver" , "Call; eg, mobile" , "Communication device" , "Mobile, perhaps" , "Covert monitoring of electronic exchanges" .)
