Tied in a knot, she gets hot! (5)
I believe the answer is:
edith
'tied in a knot she gets hot' is the definition.
I can't tell whether this defines the answer.
'tied in a knot she gets hot' is the wordplay.
I cannot really understand how this works, but
an anagram of 'tied' is 'edit' which is located in the answer.
'hot' could be 'h' (abbreviation eg on taps) and 'h' is found in the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for edith that I've seen before include "Woman's name" , "Female name" , "Woman" , "Dame ----- Evans (1888-1976), stage and screen actress" , "Cavell, Piaf or Wharton" .)
