Rodent bites son — it’s hair-raising? (6)
I believe the answer is:
mousse
'it's hair-raising?' is the definition.
I can't judge whether this defines the answer.
'rodent bites son' is the wordplay.
'rodent' becomes 'mouse' (mouse is a kind of rodent).
'bites' is an insertion indicator.
'son' becomes 's' (genealogical abbreviation for son).
'mouse' going around 's' is 'MOUSSE'.
Can you help me to learn more?
(Other definitions for mousse that I've seen before include "Something for the hair" , "Whipped savoury dish" , "Capital preparation" , "Frothy, creamy dessert" , "Whipped cream dessert" .)
