Root — English definition

Defined in 3 courses:

Where it is taught

In use

A huge share of English — especially the long words in science and history — is built from a small set of Greek and Latin roots, and each root keeps its meaning wherever it lands.

Context Clues & Word-Solving

Affixes — prefixes and suffixes — then bend a root's meaning: the prefix 'in-' can negate ('incredible' = not believable), 'circum-' means 'around' ('circumnavigate' = sail around), and a suffix like '-tion' turns a verb into a noun.

Vocabulary in Context

A root is the core piece that carries a word's central meaning, and a single root can unlock a dozen words at once.

Vocabulary & Word Analysis

Questions using root

Problem 1

The root 'aud' means 'hear.' Which word does NOT use that root's meaning?
  1. auction
  2. audience
  3. audible
  4. auditorium
Answer and explanation

auction

'Audience' (people who hear), 'audible' (able to be heard), and 'auditorium' (a place built for hearing) all use 'aud' to mean hearing. 'Auction,' a public sale, has nothing to do with hearing.

Problem 2

The prefix 'pre-' means 'before' and the root 'view' means 'see.' Explain what a 'preview' most likely is, and describe how you could confirm your answer.
Answer and explanation

A preview is a look at something before the full thing — like seeing a short clip of a movie before it comes out — combining 'pre-' (before) and 'view' (see). You could confirm this by checking a dictionary, which would give the precise meaning and the part of speech (noun or verb).

Problem 3

The root 'spect' means 'look' and 'circum-' means 'around.' Based on this, what does 'circumspect' most likely describe?
  1. Someone who never looks at anything.
  2. A type of circular object.
  3. Someone who speaks very loudly.
  4. Someone who looks around carefully before acting; cautious.
Answer and explanation

Someone who looks around carefully before acting; cautious.

'Circum-' (around) plus 'spect' (look) builds the meaning 'looking around carefully' — that is, cautious and watchful.

Problem 4

The root 'spect/spec' appears in inspect, spectator, and perspective. What does it most likely mean?
  1. to speak
  2. to look or see
  3. to build
  4. to move
Answer and explanation

to look or see

All three words involve looking — inspect (look into), spectator (one who watches), perspective (a way of seeing) — so 'spect/spec' means 'to look.'
