Lingerie that is not here to stay (6)
I believe the answer is:
linger
'to stay' is the definition.
(I know that linger is a more specific form of the action persist)
'lingerie that is not' is the wordplay.
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'not' suggests deleting specific letters.
'lingerie' with 'ie' taken out is 'LINGER'.
'here' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for linger that I've seen before include "Leave slowly and hesitantly" , "Procrastinate" , "Stay behind" , "Dawdle, hang around" , "Be slow to leave" .)
