Drawn in a number of ways (5)
I believe the answer is:
tense
'drawn' is the definition.
(I've seen this before)
'number of ways' is the wordplay.
'number' becomes 'ten' (ten is a kind of number).
'of ways' becomes 'se' (I am not sure about this - if you are sure you should believe this answer much more).
'ten'+'se'='TENSE'
'in a' acts as a link.
Can you help me to learn more?
(Other definitions for tense that I've seen before include "edgy" , "Charged" , "Maybe future" , "Rigid, or grammatical time" , "Stretched tightly, unable to relax" .)
