Most peculiar aspect of childhood destiny (6)

I believe the answer is:

oddest

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

'most peculiar' is the definition.
(I've seen this before)

'of childhood destiny' is the wordplay.
'of' indicates a hidden word.
'ODDEST' is hidden in the letters of 'childhood destiny'.

'aspect' is the link.
I am not very happy about this link. It may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for oddest that I've seen before include "most bizarre" , "Most rum" , "Most curious or unusual" , "Most eccentric or peculiar" , "Strangest" .)

I've seen this clue in The Telegraph.
