See woman endlessly dancing? Impressive (7)
I believe the answer is:
awesome
'impressive' is the definition.
(similar in meaning)
'see woman endlessly dancing?' is the wordplay.
'endlessly' means to remove the last letter.
'dancing?' is an anagram indicator.
'see'+'woman'='seewoman'
'seewoman' with its last letter taken away is 'seewoma'.
'seewoma' anagrammed gives 'AWESOME'.
(Other definitions for awesome that I've seen before include "Very imposing, inspiring wonder" , "Hugely impressive, creating fear and wonder" , "Breathtaking" , "Impressive - formidable" , "Totally cool!" .)
