Suggest Auntie's in trouble (9)
I believe the answer is:
insinuate
'suggest' is the definition.
(insinuating is a kind of suggesting)
'auntie's in trouble' is the wordplay.
'trouble' indicates anagramming the letters.
'aunties'+'in'='auntiesin'
'auntiesin' is an anagram of 'INSINUATE'.
(Other definitions for insinuate that I've seen before include "Intimate, imply" , "Indirectly suggest (something unpleasant)" , "Suggest by indirect means" , "Hint" , "Intimate with annuities" .)
