And in the holds, working, are the experienced people (3,5)
I believe the answer is:
old hands
'the experienced people' is the definition.
'old hands' can be an answer for 'people' (old hand is a kind of person). I'm unsure of the 'the experienced' bit.
'and in the holds working' is the wordplay.
'in' is an insertion indicator.
'working' indicates anagramming the letters.
'holds' anagrammed gives 'oldhs'.
'and' placed inside 'oldhs' is 'OLD HANDS'.
'are' is the link.
Can you help me to learn more?
(Other definitions for old hands that I've seen before include "Experienced persons" , "Veterans" , "Experts" , "experienced types" , "Experienced people who have given long service" .)
