I render translation more like a dweeb (7)

I believe the answer is:

nerdier

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

'more like a dweeb' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'i render translation' is the wordplay.
'translation' indicates anagramming the letters.
'i'+'render'='irender'
'irender' anagrammed gives 'NERDIER'.

Can you help me to learn more?
