Flippant member of the A-Team promises to pay overtime (9)
I believe the answer is:
facetious
'flippant' is the definition.
(I've seen this before)
'promises to pay overtime' is the wordplay.
'promises' becomes 'IOUs' (promises to pay a debt).
'to' says to put letters next to each other (I've seen this in other clues).
'pay overtime' becomes 'facet' (I can't explain this - if you can you should believe this answer much more).
'ious' after 'facet' is 'FACETIOUS'.
'member of the a-team' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for facetious that I've seen before include "Inappropriately humorous" , "Jocular; frivolous" , "Flippantly humorous" , "Intended to be amusing or witty" , "Using inapt humour" .)
