Jumpers and anoraks go tatty (9)

Ross

I believe the answer is:

kangaroos

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

'jumpers' is the definition.
Although both the answer and definition are plural nouns, I don't see how one could define the other.

'anoraks go tatty' is the wordplay.
'tatty' indicates an anagram.
'anoraks'+'go'='anoraksgo'
'anoraksgo' anagrammed gives 'KANGAROOS'.

'and' is the link.

Can you help me to learn more?

(Another definition for kangaroos that I've seen is " Large leaping mammals".)

I've seen this clue in The Telegraph.
