Clear, get somewhat ridiculously backward (5)
I believe the answer is:
lucid
'clear' is the definition.
(similar in meaning)
'somewhat ridiculously backward' is the wordplay.
'somewhat' indicates the answer is hidden within the clue.
'backward' is a reversal indicator.
'dicul' can be found hidden inside 'ridiculously'.
'dicul' written backwards gives 'LUCID'.
'get' acts as a link.
(Other definitions for lucid that I've seen before include "Cogent" , "Clearly expressed; sane" , "Clear; bright" , "Clear, intelligible" , "Clear-cut" .)
