dialect and accent: An accent is simply how one pronounces words—a style of pronunciation. A dialect includes not just pronunciations, but also one’s general vocabulary and grammar
idiolect is the language of a single individual (language which one person has made up for their own use only).
cognate: Cognates are words in two languages that share a similar meaning, spelling, and pronunciation.
homonym, homophone, homograph: Homophones are words that sound the same but are different in meaning or spelling. Homographs are spelled the same, but differ in meaning or pronunciation. Homonyms can be either or even both.
creole: is a stable natural language that develops from the simplifying and mixing of different languages into a new one within a fairly brief period of time: often, a pidgin evolved into a full-fledged language. For example, English has many creole language variations, like Manglish (Malaysian English), Singlish (Singapore English) etc.
