What are the 8 parts of a dictionary?

A dictionary is a collection of Words in one or more specific languages, listed alphabetically and accompanied by other information like definition and etymologies. There are different parts of a dictionary entry which are used to let people understand a particular Word better. There is the entry Word, the pronunciation key, the part of speech, its date of origin, the main definition of the Word, followed by other secondary or alternate definitions, and sometimes by other versions of the same Word.
