Bubbly female mostly undecided over hubby after vacation (6)
I believe the answer is:
frothy
'bubbly' is the definition.
(I know that bubbly can be written as frothy)
'female mostly undecided over hubby after vacation' is the wordplay.
'female' becomes 'f' (abbreviation).
'mostly' means to remove the last letter (most but not all of the word).
'undecided' becomes 'torn' (someone deliberating between two options is torn).
'over' is a reversal indicator.
'after vacation' says to hollow out the word (remove centre letters) (the inside letters must vacate).
'hubby' with its middle removed is 'hy'.
'torn' with its last letter taken off is 'tor'.
'tor' back-to-front is 'rot'.
'f'+'rot'+'hy'='FROTHY'
(Other definitions for frothy that I've seen before include "Very bubbly" , "Foamy; insubstantial" , "Covered with foam, like superficial talk" , "Foaming" , "Sudsy" .)
