Like a tonsure one can have in different ways (6)
I believe the answer is:
shaven
'like a tonsure one' is the definition.
I can't judge whether this definition defines the answer.
'have in different ways' is the wordplay.
'in' means one lot of letters goes inside another.
'different ways' becomes 'sn' (I can't justify this - if you can you should believe this answer much more).
'have' going inside 'sn' is 'SHAVEN'.
'can' is the link.
Can you help me to learn more?
(Other definitions for shaven that I've seen before include "Without a beard" , "without locks" , "Hairless after work with razor" , "With hair removed (N, not D)" , "lacking coverage" .)
