Wave hairpiece? (6)
I believe the answer is:
roller
'wave hairpiece?' is the definition.
'roller' can be an answer for 'wave' (I've seen this before). I am not certain of the 'hairpiece?' bit.
'wave hairpiece?' is the wordplay.
'wave' becomes 'roll' (roll is a kind of wave).
'hairpiece?' becomes 'er' (I can't justify this - if you can you should believe this answer much more).
'roll'+'er'='ROLLER'
Can you help me to learn more?
(Other definitions for roller that I've seen before include "Long heavy sea wave" , "Big wave or hair setter" , "A large wave or a hair shaper" , "Cylinder for flattening etc" , "Large wave or hair curler" .)
