Having military dress on, name to be sewn in in the dark (10)
I believe the answer is:
uninformed
'in the dark' is the definition.
(I've seen this in another clue)
'having military dress on name to be sewn in' is the wordplay.
I cannot really understand how this works, but
'name' could be 'ed' (short for Edward) and 'ed' is located in the answer.
'to' could be 'for' and 'for' is found in the answer.
'in' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for uninformed that I've seen before include "Not knowledgeable" , "in the dark" , "Missing dope" , "Lacking intelligence" .)
