Be slow to show abhorrence about fancy ties (8)
I believe the answer is:
hesitate
'be slow to' is the definition.
I can't judge whether this definition defines the answer.
'abhorrence about fancy ties' is the wordplay.
'abhorrence' becomes 'hate' (I've seen this in another clue).
'about' means one lot of letters goes inside another.
'fancy' is an anagram indicator.
'ties' with letters rearranged gives 'esit'.
'hate' enclosing 'esit' is 'HESITATE'.
'show' acts as a link.
Can you help me to learn more?
(Other definitions for hesitate that I've seen before include "'Pause, dither (8)'" , "Delay making a decision" , "Falter, delay" , "Dither, waver" , "To do so is to be lost, they say" .)
