tom

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

This clue might be a double definition.

'ginger' is the first definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.

'boy?' is the second definition.

Can you help me to learn more?

(Other definitions for tom that I've seen before include "Queen's mate" , "- Lehrer, US humorist" , "Male beast" , "Edgar's Poor disguise (Lear)" , "Boy - cat" .)

I've seen this clue in the Evening Standard.
