Wave or wave-maker? (6)
I believe the answer is:
roller
'wave' is the definition.
(I know that roller is a type of wave)
'wave-maker?' is the wordplay.
'wave' becomes 'roll' (roll is a kind of wave).
'maker?' becomes 'er' (I am not sure about this - if you are sure you should believe this answer much more).
'roll'+'er'='ROLLER'
'or' acts as a link.
Can you help me to learn more?
(Other definitions for roller that I've seen before include "Wave - wave-maker" , "One might be used for painting" , "road maintenance vehicle" , "Cylinder for curling the hair" , "Big wave or hair setter" .)
