For cutting out clients' letters? (7)
I believe the answer is:
stencil
'for cutting out' is the definition.
I can't tell whether this definition defines the answer.
'clients' letters?' is the wordplay.
'letters?' indicates an anagram (I've seen 'letters' mean this).
'clients' anagrammed gives 'STENCIL'.
Can you help me to learn more?
(Other definitions for stencil that I've seen before include "Cut-out for applying ink" , "Make patterns using thin perforated sheets" , "Design inked through perforated sheet" , "Cut-out pattern for applying paint" , "Perforated sheet for producing patterns or symbols" .)
