Left omen out about citrus (5)

Ross

I believe the answer is:

lemon

'citrus' is the definition.
(I know that lemon is a type of citrus)

'left omen out about' is the wordplay.
'left' becomes 'l' (common abbreviation).
'out' is an anagram indicator (out can mean wrong or inaccurate).
'about' means one lot of letters goes inside another.
'omen' anagrammed gives 'emon'.
'l' inserted within 'emon' is 'LEMON'.

(Other definitions for lemon that I've seen before include "Tone" , "Fruit - as an answer it's unsatisfactory" , "Useless object" , "Shade of yellow - fruit" , "something defective" .)

I've seen this clue in The Mirror.
