Which term denotes a continuum used to illustrate gradable antonyms in language teaching?

• A. Lexical field
• B. Cline
• C. Semantic network
• D. Taxonomy

Answer: (B)

Gradable antonyms sit on a scale, not as strict opposites. To teach this idea clearly, we use a continuum that shows intermediate degrees of a quality—this is called a cline. A cline helps learners see how language expresses more or less of a property and where different terms fit on that gradient. For example, in a teaching context you might place warm, warmer, and hot along a line to illustrate increasing degree, or cold, cool, and warm to show opposite directions on the same scale. This visualizes how words differ in intensity and where to choose one term over another in context.

The other terms point to different concepts: a lexical field groups words around a topic, a semantic network maps relationships between meanings, and a taxonomy is a hierarchical classification.
