Creamy confection in seconds consumed by timid person (6)
I believe the answer is:
mousse
'creamy confection' is the definition.
'mousse' can be an answer for 'confection' (thesaurus). I'm not certain of the 'creamy' bit.
'seconds consumed by timid person' is the wordplay.
'seconds' becomes 's' (abbreviation).
'consumed by' indicates putting letters inside (inserted letters get consumed).
'timid person' becomes 'mouse' (I've seen this in another clue).
's' inserted into 'mouse' is 'MOUSSE'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for mousse that I've seen before include "Whipped sweet" , "Fluffy pudding" , "Dish; hair preparation" , "Foamy dish" , "hair product" .)
