eg Owl pursuing pussycat that's possibly ours, grabbing it (6)
I believe the answer is:
suitor
'eg owl pursuing pussycat' is the definition.
I can't tell whether this definition defines the answer.
'possibly ours grabbing it' is the wordplay.
'possibly' is an anagram indicator.
'grabbing' is an insertion indicator.
'ours' is an anagram of 'suor'.
'suor' going around 'it' is 'SUITOR'.
'that's' is the link.
Can you help me to learn more?
(Other definitions for suitor that I've seen before include "A man wooing" , "Man who is courting a woman" , "Wooer" , "Prospective husband" , "He woos a maid" .)
