Khmer Consonants and their Subscripts

Here are the subscripts. Most of the subscript subscript looks similar to the normal consonant, with few minor exception.
For now, I just want you to know all the consonsants and their subscript. The subscript put emphases on the consonant. You can still read the word without the subscript, but when it comes to spelling out some words you need the subscript.
Next, I'll show you how to write some of the subscript that does not look like there normal consonants.
