Cause of spot of bother on country walk? (7)

Ross

I believe the answer is:

bramble

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

'cause' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.

'spot of bother on country walk?' is the wordplay.
'spot of' indicates taking the first letters.
'on' is a charade indicator (letters next to each other).
'country walk?' becomes 'ramble' (I've seen this before).
The first letter of 'bother' is 'b'.
'b'+'ramble'='BRAMBLE'

'of' is the link.

Can you help me to learn more?

(Other definitions for bramble that I've seen before include "Thorny bush" , "Source of fruit" , "berries" , "Blackberry plant" , "Dog rose" .)
