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

'some of' is the definition.
The definition suggests a singular noun which matches the answer.

Can you help me to learn more?

(Other definitions for pass that I've seen before include "change" , "Ratify for saps" , "way through mountains" , "Amorous advance" , "Go by; mountain route" .)

I've seen this clue in the Irish Times (Crosaire) and the Irish Times.
