"Linguistic theories generally regard human languages as consisting of two parts: a lexicon and a grammar."
"The lexicon is a language's inventory of lexemes, essentially a catalogue of a language's words."
"A lexicon, essentially a catalogue of a language's words, and a grammar, a system of rules which allow for the combination of those words into meaningful sentences."
"The lexicon is thought to include bound morphemes, which cannot stand alone as words."
