It's entering in a way that's exciting attention (11)
I believe the answer is:
interesting
'exciting attention' is the definition.
'interesting' can be an answer for 'exciting' (thesaurus). I am not certain of the 'attention' bit.
'it's entering in a way' is the wordplay.
'in a way' indicates anagramming the letters.
'its'+'entering'='itsentering'
'itsentering' anagrammed gives 'INTERESTING'.
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for interesting that I've seen before include "Curious" , "Gripping" , "Arousing curiosity" , "Arousing attention" , "worthy of note" .)
