English has a vast collection of words and often we have to consult a dictionary to learn the meaning of them. The basic units of the language are the letters of the alphabet. The alphabet consists of 5 vowels and 21 consonants which have specific symbols for easy identification. Each letter also has a specific sound that is used for pronunciation. Groups of letters are arranged in a specific order to complete words and these orders are called spellings.
Spellings determine the unique identity of each word and specific sounds determine its pronunciation. Words are then put together in a specific order to form a sentence which conveys a unit of information. Several sentences are grouped in a paragraph and several paragraphs constitute a complete message or idea.
