Which expression is a classic example of a formulaic chunk learned as a whole?

• A. Once upon a time
• B. To some extent
• C. In conclusion
• D. On the other hand

Answer: (A)

Formulaic chunks are fixed phrases that you learn and use as a single unit rather than piecing them together word by word. Once upon a time fits this idea perfectly: it’s a traditional story opener that learners memorize as one chunk because its meaning and usage are tied to a specific storytelling function. It signals the start of a tale and is commonly used exactly as written, without altering the sequence of words. The other phrases are useful transitional or stance markers, but they’re more flexible in form and meaning; they can be replaced or paraphrased and still perform their function, so they aren’t as clearly learned as a single, indivisible unit.
