Perhaps we sat there, darling (10)
I believe the answer is:
sweetheart
'darling' is the definition.
(I've seen this before)
'perhaps we sat there' is the wordplay.
'perhaps' indicates an anagram.
'we'+'sat'+'there'='wesatthere'
'wesatthere' anagrammed gives 'SWEETHEART'.
(Other definitions for sweetheart that I've seen before include "Beloved" , "Darling" , "Lover" , "Dear" , "Boy- or girlfriend" .)
