Female at Hebridean isle? (5)

I believe the answer is:

fiona

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

'female at hebridean isle?' is the definition.
I can't judge whether this definition defines the answer.

'female at hebridean isle?' is the wordplay.
'female' becomes 'f' (common abbreviation).
'at' means one lot of letters go next to another.
'hebridean isle?' becomes 'iona' (I've seen this in another clue).
'f'+'iona'='FIONA'

Can you help me to learn more?

(Other definitions for fiona that I've seen before include "Girl" , "Girl's name, meaning fair in Gaelic" , "Girl's name (not Flora)" .)

I've seen this clue in The Times.
