Which term best describes a fixed expression that cannot be understood by analyzing its parts alone?

• A. Multi-word units
• B. Mistake/slip
• C. Global error
• D. Pre-systemic error

Answer: (A)

Fixed expressions that can’t be understood by analyzing their parts are best described as multi-word units. These are chunks of language—like idioms or collocations—that function as a single unit, and their meaning isn’t reliably derived from the individual words. For example, “spill the beans” means to reveal a secret, a meaning you wouldn’t predict from “spill” and “beans” alone. Language learners benefit from recognizing these as whole units rather than trying to infer meaning from each word. The other options refer to types of errors or non-literal slips, not to fixed expressions as lexical chunks. A mistake or slip is a production error, not a memorized unit. Global error describes a broad mistake affecting an entire sentence, and a pre-systemic error relates to incorrect interlanguage before the learner’s system stabilizes. None of these capture the idea of a fixed, indivisible expression whose meaning isn’t predictable from its parts.
