Could one confuse it with melon? (5)

I believe the answer is:

lemon

I'm a little stuck... Click here to teach me more about this clue!

'could one confuse it' is the definition.
I can't judge whether this defines the answer.

'melon?' is the wordplay.
'melon' anagrams to 'LEMON'.
But, I'm unsure how the anagram is indicated.

'with' acts as a link.

Can you help me to learn more?

(Other definitions for lemon that I've seen before include "Leaving body" , "Strong yellow colour" , "very different from peach?" , "stinker" , "Dab" .)

I've seen this clue in the Evening Standard.
