The four rules of language are phonemes, lexemes, syntax, and semantics.
In speech, a morpheme is a sound. The lowest unit of sounds that separates one word from the other is called a phoneme. Due to the fact that sounds cannot be written, we use letters to represent or stand for them.A grapheme is a letter or group of characters that represents a single sound in writing.
A phoneme is a sound that can be heard in a word. It is the smallest chunk of sound that constitutes a whole word. Phonemes are merely sounds; they should not be confused with letter itself. It's crucial to realize that phonemes might contain multiple characters.
