How does technical language function in informational texts, and when is it appropriate to define terms?

• A. Technical terms should always be avoided to simplify reading.
• B. They are decorative and have no impact on meaning.
• C. They should be defined only in a glossary.
• D. Technical terms convey precise meaning; define them when first introduced or when readers may be unfamiliar.

Answer: (D)

Technical terms carry precise meanings that help share exact ideas in informational texts. They’re not just fancy words; they anchor the writer’s meaning and show how concepts relate to one another. Because readers may not know every specialized term right away, it’s best to define them when they first appear, or if a term is likely to be unfamiliar to the audience. A quick definition right at introduction or a simple context clue helps readers grasp the concept immediately, and it keeps later references clear without unnecessary repetition. If several terms are used, a glossary or a short note can support understanding, but the key moment is the first introduction or whenever confusion might arise.
