After school exam, finally escape for a chat (8)
I believe the answer is:
schmooze
'for a chat' is the definition.
(to schmooze is to chat informally)
'after school exam finally escape' is the wordplay.
'after school' becomes 'sch' (common abbreviation. I am not sure about the 'after' bit.).
'finally' suggests the final letters.
'escape' becomes 'ooze'.
The last letter of 'exam' is 'm'.
'sch'+'m'+'ooze'='SCHMOOZE'
Can you help me to learn more?
(Other definitions for schmooze that I've seen before include "chatter" , "Chat in friendly manner" , "Talk intimately in order to manipulate" , "circulate" , "Chat socially" .)
