To be heavier than two huge bananas one's eaten (8)
I believe the answer is:
outweigh
'to be heavier than' is the definition.
I can't tell whether this defines the answer.
'two huge bananas one's eaten' is the wordplay.
'bananas' indicates an anagram (bananas can informally mean crazy).
'one' becomes 'i' (Roman numeral).
'eaten' means one lot of letters goes inside another.
'two'+'huge'='twohuge'
'twohuge' is an anagram of 'outwegh'.
'outwegh' placed around 'i' is 'OUTWEIGH'.
Can you help me to learn more?
(Other definitions for outweigh that I've seen before include "Override" , "Be heavier or more significant than" , "Be more important or heavier than" , "trump?" , "dated fashion, we hear" .)
