Calling social worker to meet reticent person (7)
I believe the answer is:
clamant
'calling social' is the definition.
Both the answer and definition are adjectives. Maybe you can see a link between them that I don't see?
'worker to meet reticent person' is the wordplay.
'worker' becomes 'ant' (worker is a type of ant).
'to meet' is a charade indicator (letters next to each other).
'reticent person' becomes 'clam' (clam can figuratively mean a shy person).
'ant' put after 'clam' is 'CLAMANT'.
Can you help me to learn more?
(Other definitions for clamant that I've seen before include "Loudly vocal" , "Noisy" , "Calling out" , "demanding urgent attention" , "Malt can (anag.)" .)
