Skinny daughter sacrificing anything to be a dedicated swimmer (7)

I believe the answer is:

leander

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

'a dedicated swimmer' is the definition.
'leander' can be an answer for 'swimmer' (I've seen this before). I am not sure about the 'a dedicated' bit.

'skinny daughter sacrificing anything' is the wordplay.
'skinny' becomes 'lean' (similar in meaning).
'sacrificing' suggests deleting specific letters.
'anything' becomes 'aught' ('aught' means anything).
'daughter' with 'aught' taken out is 'der'.
'lean'+'der'='LEANDER'

'to be' acts as a link.

Can you help me to learn more?

(Other definitions for leander that I've seen before include "Oarsmen" , "Hero's mate" , "Ill-fated lover" , "long-distance swimmer" , "Learned Greek lover who swam Hellespont to meet Hero" .)
