Learn French: La haine est allée trop loin sur le forum.

The word haine begins with an "aspirated h" (h aspiré). While the "h" itself is totally silent, it acts like a consonant. This means you cannot drop the vowel (elision) of the word before it, unlike words with a mute h such as l'homme or l'hôpital.

Why is there an extra e at the end of allée?

The verb aller (to go) is conjugated with the auxiliary verb être in the passé composé. When a verb uses être, its past participle has to agree in gender and number with the subject. Because the subject La haine is feminine and singular, allé becomes allée.

Can aller be used for abstract concepts like hate?

Yes! Just like in English ("went too far"), aller is perfectly natural to use for figurative or abstract progression in French, not just physical travel.

Why do we use the preposition sur for a forum?

In French, sur (on) is the standard preposition for almost everything related to the internet, screens, and digital platforms. You will commonly see it in phrases like sur le forum, sur Internet, or sur mon téléphone.
