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

'one' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'five in hovel not seeing straight' is the wordplay.
I cannot quite understand how this works, but
'five' could be 'quint' (synonyms) and 'quint' is present in the answer.
This explanation may well be incorrect...

'of' acts as a link.
