Wait for call in AE (5)
I believe the answer is:
abide
'wait for' is the definition.
(I've seen this before)
'call in ae' is the wordplay.
'call' becomes 'bid' (synonyms).
'in' indicates putting letters inside.
'bid' inserted inside 'ae' is 'ABIDE'.
(Other definitions for abide that I've seen before include "Stomach" , "Remain - tolerate" , "Tolerate - dwell" , "lodge" , "Wait for" .)
