In a normal dictionary, you are given the meaning, pronunciation, different parts of speech and the origin (also referred to as etymology).
Lexical terms form the basic units of a language's lexicon (vocabulary).
Inflection is where a word is changed (usually at the end) to express a grammatical change.
