Dicky simpers to grab attention (7)
I believe the answer is:
impress
'grab attention' is the definition.
'impress' can be an answer for 'grab' (thesaurus). I am unsure of the 'attention' bit.
'dicky simpers' is the wordplay.
'dicky' indicates anagramming the letters (dicky can mean ill or non-functioning).
'simpers' anagrammed gives 'IMPRESS'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for impress that I've seen before include "look big?" , "Move, affect" , "Imprint" , "Earn good opinion of, or stamp" , "Make one's mark (on)" .)
