Coherent US soldier going into pub (7)
I believe the answer is:
logical
'coherent' is the definition.
(I've seen this before)
'us soldier going into pub' is the wordplay.
'us soldier' becomes 'gi' (I've seen this in other clues).
'going into' means one lot of letters goes inside another.
'pub' becomes 'local' (I've seen this before).
'gi' placed inside 'local' is 'LOGICAL'.
(Other definitions for logical that I've seen before include "Consistent with reason" , "Well-reasoned" , "Deductive" , "According with reason" , "Showing rational thought" .)
