Build channel again and cut down on staff (8)
I believe the answer is:
retrench
'cut down on staff' is the definition.
'retrench' can be an answer for 'cut' (retrenching is a kind of cutting). I'm not sure about the 'down on staff' bit.
'build channel again' is the wordplay.
I cannot really understand how this works, but
'channel' could be 'trench' (I've seen this in another clue) and 'trench' is located in the answer.
'again' could be 're' (prefix meaning 'again') and 're' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for retrench that I've seen before include "Reduce one's workforce" , "Cut back expenses" , "Cut back, tighten one's belt" , "Bring down" , "Cut back spending" .)
