Light left on, get into the unmade bed (6)
I believe the answer is:
blonde
'light' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'left on get into the unmade bed' is the wordplay.
'left' becomes 'l' (common abbreviation).
'get into' means one lot of letters goes inside another.
'the unmade' indicates an anagram (the original order is unmade or damaged).
'l'+'on'='lon'
'bed' is an anagram of 'bde'.
'lon' placed inside 'bde' is 'BLONDE'.
Can you help me to learn more?
(Other definitions for blonde that I've seen before include "Kind of fair girl" , "Fair-headed" , "Light-haired woman" , "Fair lady" , "What may follow Strawberry" .)
