Offer to pay for newcomer in the US (10)
I believe the answer is:
tenderfoot
'newcomer in the us' is the definition.
'tenderfoot' can be an answer for 'newcomer' (I've seen this before). I am not sure about the 'in the us' bit.
'offer to pay' is the wordplay.
'offer' becomes 'tender' (tender can mean to offer something).
'to pay' becomes 'foot' (as in footing the bill).
'tender'+'foot'='TENDERFOOT'
'for' is the link.
Can you help me to learn more?
(Other definitions for tenderfoot that I've seen before include "new employee of mine" , "one still finding her bearings" , "Newcomer, novice" , "Raw recruit" , "Novice (chiefly US)" .)
