Giving a party is trying (6,1,4)

I believe the answer is:

having a bash

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

'trying' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'giving a party' is the wordplay.
'giving' becomes 'having' ('have' can be a synonym of 'give').
'party' becomes 'bash' (term for a party or celebration).
'having'+'a'+'bash'='HAVING A BASH'

'is' is the link.

Can you help me to learn more?
