Final answer:
Low-frequency words are those not commonly used in everyday language and might appear in specialized or technical contexts. They are not restricted to a single domain and can be relevant in any content area. When writing, it's important to consider the word's appropriateness for the text, audience, and cultural sensitivity.
Step-by-step explanation:
Low-frequency words are terms that occur less frequently in written or spoken language. They are not necessarily limited to a specific domain and can pertain to various content areas, though they may be more prevalent in technical or specialized texts where unique vocabulary is often used. Questions to consider when choosing the right words for a text include: 1) Am I sure this is the right word to express my idea? 2) To the best of my knowledge, did I spell it correctly? Ensure that the word is suitable for the text and audience, and remember that if there is uncertainty about the word, an alternative might be available. Also, consider whether the language used could be offensive or if it suits the language preferences of a specific group. Finally, make sure the writing is accessible to people of various abilities.
