What is dictionary pronunciation key?

A dictionary pronunciation key is a set of symbols and conventions used to represent the sounds of words in a language. It typically includes a table or chart that lists the symbols along with their corresponding sounds. The pronunciation key is designed to help readers of a dictionary to correctly pronounce the words they encounter. Some common symbols used in pronunciation keys include the International Phonetic Alphabet (IPA) symbols, as well as other recognizable symbols such as apostrophes, hyphens, and diacritical marks. The pronunciation key may also provide guidance on stress patterns, syllable breaks, and other aspects of pronunciation.
