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

'beer that has been diluted' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see an association between them that I don't see?

'suspicious about head on northerner's' is the wordplay.
'suspicious' becomes 'shady' (synonyms).
'about' is an insertion indicator.
'head on' suggests taking the first letters.
The initial letter of 'northerners' is 'n'.
'shady' enclosing 'n' is 'SHANDY'.

Can you help me to learn more?
