Cowboy might throw this girl over (5)

I believe the answer is:

lasso

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

'cowboy might throw this' is the definition.
The definition suggests a singular noun which matches the answer.

'girl over' is the wordplay.
'girl' becomes 'lass' (lass can informally mean a girl).
'over' becomes 'o' (cricket abbreviation).
'lass'+'o'='LASSO'

Can you help me to learn more?

(Other definitions for lasso that I've seen before include "Looped rope used to catch cattle" , "Cattle-catching rope" , "Rancher's rope" , "Cow catcher" , "Rope for catching livestock" .)
