I believe the answer is:

rarity

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

'curiosity' is the definition.
(I know that curiosity can be written as rarity)

'i tarry perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'i'+'tarry'='itarry'
'itarry' is an anagram of 'RARITY'.

'and discover a' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?

(Other definitions for rarity that I've seen before include "You don't see it very often" , "Uncommon thing" , "Something seldom seen" , "Unusual thing" , "Something valued for its scarceness" .)

I've seen this clue in The Globe and Mail.
