Find uniform by Thursday (7)
I believe the answer is:
unearth
'find' is the definition.
(I know that locate is the is a more specific form of the action of unearth.)
'uniform by thursday' is the wordplay.
'uniform' becomes 'U' (phonetic alphabet: alpha, bravo, charlie etc.).
'by' becomes 'near' (I've seen this in another clue).
'thursday' becomes 'Th' (common abbreviation).
'u'+'near'+'th'='UNEARTH'
(Other definitions for unearth that I've seen before include "Disconnect terminal" , "reveal" , "Bring out of obscurity" , "Excavate, dig up" , "Dig up - uncover" .)
