Thai children learn the letter by its full name, บ ใบไม้ bo bai mai, picture and all. Say the whole thing and the shape comes with it.

What its class does to the tone

Mid class is the smallest group and the only one that can take all four tone marks. With no mark it gives a mid tone on a live syllable and a low tone on a dead one. These three lines cover most of what you will meet, and they hold for บ exactly as they do for every other mid-class letter.

live syllable, no mark mid tone กา gaa
dead syllable, no mark low tone กด gòt
with mai ek low tone จ่าย jài

The examples are whichever mid-class word shows the rule most clearly. The full grid for all three classes is here.

Letters that sound the same

Nothing else makes this sound. บ is the only letter that gives "b" at the start of a syllable, which is worth knowing before you meet the letters that do share one.

Easy to mix up with

Each pair differs by one stroke, and each mistake changes the word.
