In the English language, some alphabets are pronounced and spelled differently, which results in the incorrect pronunciation of the words.We all tend to pronounce the words as they are spelled. For this, there should be a clear distinction between letters and sounds.The phonemes are the distinctive sound unit in a spoken language.Phonemes:The basic building blocks of a language are called phonemes. They are the smallest unit of sounds in a language.A phoneme does not have any inherent meaning by itself, but when you put phonemes together, they can make words. It is the sound system that is being represented by slash marks conventionally such as the phonemes of the word "cat" can be represented as /c/, /a/, /t/. A phoneme is a sound in a language that has its own distinct sound. There are 44 phonemes (sounds) in the English language. There are 24 consonants and 20 vowel sounds in the English language.Hence, it is clear that one of the basic building blocks of a language is Phoneme.Hint Morpheme is a word or a part of a word that has meaning. It cannot be divided into smaller meaningful segments without changing its meaning or leaving a meaningless remainder.Grapheme is a symbol used to identify a phoneme; it's a letter or group of letters representing the sound. Eg- There are 4 letters(w,e,e,k) in the word week but Grapheme are three (w, 'ee', k) in the word week.Linguistics is the science of language. It describes the sounds used in a language to build the utterances. It studies the way the meaningful units of language (morphemes, words, etc.) combine to produce meaningful sentences.
