I don't know who that youngster is.

Je ne sais pas qui est ce jeune homme.

She saved the youngster!

Elle a sauvé l'enfant !

Who do you think you're talking to, youngster?

Tu crois parler à qui, petit insolent ?

I began to sing when I was a youngster.

J’ai commencé à chanter quand j’étais jeune.

Yeah, my youngster did that.

Ouais, mon gamin a fait ça.
