2. Verb Forms
The Fench verb system is probably the most difficult part of the French language for learners. It is very complicated with many forms that have to be simply memorized. Verb conjugation in English is a piece of cake compared to French. For example, look at the present tense of "to go" and its French equivalent, "aller."
I go, you go, he/she/it goes, we go, they go
je vais, tu vas, il/elle/on va, nous allons, vous allez, ils/elles vont
You notice that the English verb form varies only between go and goes whereas the French has six different forms. French also makes a distinction between the singular informal you (tu) and the singular formal (vous). But the plural form for both the informal and formal you is vous.
This verb avoir is an irregular verb, meaning that the verb endings do not follow a simple pattern. The vast majority of French verbs are regular and follow certain patterns that simplify learning the conjugations. But there are enough irregular verbs, especially among the most common verbs, to make your life miserable in the beginning.
Why is this so difficult? As the above example pointed out, there is so much more to memorize than in English. The typical mistake here is to follow the English pattern and try to use one form everywhere.
As you can well imagine, the French verb system has other complications that I won't attempt to explain here. The important point to keep in mind is that verbs are the heart of the French language and there are many forms to be learned by heart. So, keep your eyes and ears open.
