Cutting base, man needs large saw (6)
I believe the answer is:
beheld
'saw' is the definition.
(beholding is a kind of seeing)
'cutting base man needs large' is the wordplay.
'cutting' means one lot of letters goes inside another (some letters cut their way into a word).
'base' becomes 'bed' (bed is a kind of base).
'man needs' becomes 'he' (I am not sure about the 'needs' bit.**).
'large' becomes 'l'.
'he'+'l'='hel'
'bed' placed around 'hel' is 'BEHELD'.
Can you help me to learn more?
(Other definitions for beheld that I've seen before include "Seen" , "Laid eyes on" , "watched" , "Saw or observed in olden times" .)
