Which term refers to chunks whose parts never change and are used as fixed phrases?

• A. Fixed Expression
• B. Semi-Fixed Expression
• C. Collocation
• D. Word

Answer: (A)

Fixed expressions are chunks of language that you memorize and use as a single unit, with the words kept in a fixed order. They function as a whole rather than being assembled word by word each time. This matches the idea of parts that never change and are used as fixed phrases—the sequence is treated as a single phrase with a stable form. Examples include phrases like “kick the habit,” “by and large,” or “as a matter of fact,” which feel like one unit when you use them.

A semi-fixed expression allows a little variation in its components or structure, so it isn’t as rigid as a truly fixed expression. A collocation is a natural pair or group of words that tend to occur together (like “strong coffee” or “make a decision”) but isn’t treated as a single fixed unit in use. A single word is just one lexeme, not a chunk composed of multiple words used as a unit.
