I learned it
C'est ainsi que je l'ai appris.
That's how I learned it.
Peu importe comment je l'ai appris.
It doesn't matter how I learned it.
I learned it too late.
I learned it by heart.
I learned about it this morning.
Tout ce que je vous dis je l'ai appris de cet homme.
Everything I tell you, I learned from this man.
— Malcolm X (1992)
I learned it at school.
I learned it by heart.
