Utensil is part of suit (5)
I believe the answer is:
spade
'suit' is the definition.
(I have seen 'black suit' mean 'spade' so perhaps 'suit' could also mean 'spade')
'utensil is part' is the wordplay.
I cannot really understand how this works, but
'part' could be 'pad' (pad is a kind of part) and 'pad' is located in the answer.
The remaining letters 'se' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for spade that I've seen before include "Garden implement" , "Tool; playing card" , "Fictional detective" , "that has a cutting edge" , "Jack or one of a dozen others" .)
