Several word lists have been developed to provide people with a limited vocabulary either for the purpose of rapid language proficiency or for effective communication.
Spelling
The way in which letters are arranged in sequence to produce the pronunciation of a word is referred to as spelling or orthography.
Spelling is important for the purpose of using the word in writing. English spellings are difficult, with many words spelt differently from how they sound. This is obvious when examining homonyms (words which sound the same but are spelt differently). For example, the words tuff and tough are both pronounced/t^f/. The spelling of the first word in each case more closely resembles how it is pronounced.
