Mini Lesson
A dictionary is more than a list of meanings. Each entry is a carefully structured record that gives you multiple types of information about a word. Skilled readers know how to navigate an entry quickly — jumping to the etymology when they need a meaning clue, or checking the usage note when they are unsure whether a word fits a formal context.
The six key parts of a dictionary entry
- Headword — the word itself, usually in bold; shows spelling and syllable breaks
- Pronunciation key — a phonetic transcription (e.g. /ˈɔːdɪbəl/) showing how to say the word
- Part of speech — a label such as n., v., adj., or adv. that tells the word’s grammatical role
- Definition — the meaning, often numbered when a word has multiple senses
- Example sentence — a sentence showing the word used correctly in context
- Etymology — the word’s origin and history, e.g. from Latin audire (to hear)
Usage notes and corpus data
Many modern dictionaries also include a usage note explaining when or how to use the word (e.g. formal vs informal register, common collocations, or easily confused words). A corpus is a large electronic database of real texts. Corpus data shows how frequently a word actually appears in published writing — invaluable for understanding which words are everyday and which are rare or specialized.
You look up the word “audible” in a dictionary.
Which entry feature tells you that the word comes from Latin?
Once you spot the etymology, you can extend your vocabulary by searching the corpus for other words sharing the same root.
Strategy: when you encounter an unfamiliar word, read the full entry in sequence — headword → pronunciation → part of speech → definition → example sentence → etymology. The etymology often unlocks the core meaning and links the word to others you already know.
