Insect has some time to fix tie (7)
I believe the answer is:
termite
'insect' is the definition.
(I know that termite is a type of insect)
'some time to fix tie' is the wordplay.
'some time' becomes 'term' (I've seen this before).
'to fix' indicates an anagram.
'tie' with letters rearranged gives 'ite'.
'term'+'ite'='TERMITE'
'has' acts as a link.
(Other definitions for termite that I've seen before include "Ant-like insect that feeds on wood" , "Wood-eating insect" , "Wood-ant" , "Six-footer" , "Mound-building insect" .)
