Describing several languages, translator's beginning to charge (6)
I believe the answer is:
indict
'to charge' is the definition.
(I know that indict is a more specific form of the action accuse)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for indict that I've seen before include "Make written statement of charge against accused" , "Make written statement of charge or accusation" , "Accuse, prosecute" , "Make charge against an accused person" , "Charge (someone) with serious crime" .)
