I learned it
C'est ainsi que je l'ai appris.
That's how I learned it.
I learned about it this morning.
I learned it at school.
Ce que je sais sur les gens, je l'ai appris de Thomas.
What I know about people, I learned from Thomas.
— Bullet Train (2022)
I learned about it yesterday.
I learned it by heart.
I learned it too late.
