This document discusses words, meaning, and their relationship. It covers:
1. Words and meaning are related but separate entities. Words are represented mentally as lexemes while meaning involves concepts.
2. Morphemes are the smallest units of words - free morphemes can stand alone as words while bound require attachment.
3. Models of lexical access including serial search, parallel access like logogen and connectionist models, and the cohort model for word recognition.
Frequency, imageability, semantics, phonology and other factors influence word access and organization in the mental lexicon.
