Lexicon
A lexicon is a mental dictionary of knowledge that a speaker has on a particular language. Wordnet deals with nouns, verbs, adjectives, and adverbs.

➢ Nouns / Nomino
➢ Verb / Kitenzi
➢ Adjective / Kivumishi
➢ Adverb / Kielezi
The nouns, verbs, adjectives, and adverbs are grouped in synsets (a short form of the synonym set), a group of words that have synonyms or share the same meaning. Each synset represents a distinct concept or idea and is associated with a unique identifier and a definition.
