There are 26 letters in the English alphabet; the letters are the individual characters that are used to represent sounds in a written form, either individually or in combination with other letters. Letters can be either lower or upper case. The latter are the larger versions of the letters that occur at the start of a sentence or the beginning of a proper noun and the term capital letter is also widely used for them. Lower case letters are used for the other transcriptions of the word or the sentence.
"The grammar glossary is the most comprehensive I have seen on the Internet. The definitions are very clear and to the point." ~ Chris Durcan - Editor, The Language Key
