First, I gave you the reasons why to learn Thai. If you found them reasonable, let’s go further.
I must admit, the Thai grammar is much easier than the Thai spelling and pronunciation. At least it seems like that.
You remember that verbs in the Thai language don’t conjugate. They don’t change their form for number, person, mood, aspect. One of these criteria which doesn’t affect verbs is tense. Yes, tense. There are no tenses in Thai. Isn’t it a miracle?
