go towards

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

'does contribute to' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'got out a sword' is the wordplay.
'out' is an anagram indicator.
'a'+'sword'='asword'
'asword' is an anagram of 'owards'.
'got'+'owards'='GO TOWARDS'

'which' is the link.

Can you help me to learn more?

(Another definition for go towards that I've seen is " Approach".)
