Lion injured poor mule on the floor, maybe? (8)
I believe the answer is:
linoleum
'floor maybe?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'lion injured poor mule on' is the wordplay.
'injured' is an anagram indicator.
'poor' indicates anagramming the letters.
'on' means one lot of letters goes inside another (as in clothing 'on' a person).
'mule' with letters rearranged gives 'leum'.
'lion' is an anagram of 'inol'.
'inol' inserted inside 'leum' is 'LINOLEUM'.
'the' is the link.
Can you help me to learn more?
(Other definitions for linoleum that I've seen before include "Stiff floor covering" , "Impregnated fabric for the floor" , "Common floor covering, often in kitchen" , "Type of floor covering" , "Canvas-backed floor covering" .)
