I search frantically for shop worker (7)
I believe the answer is:
cashier
'shop worker' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'i search frantically' is the wordplay.
'frantically' indicates anagramming the letters.
'i'+'search'='isearch'
'isearch' anagrammed gives 'CASHIER'.
'for' is the link.
Can you help me to learn more?
(Other definitions for cashier that I've seen before include "One working till" , "Bank teller" , "Bank employee" , "one taking money" , "Shop payment taker" .)
