24. English - The Grammar of Definition: Matching Parts of Speech

When writing definitions, learners often make grammatical mistakes by failing to match the parts of speech between the term being defined and its definition. A common error is defining a noun using an adjective or a verb phrase instead of another noun. For example, writing that honesty is when you tell the truth is grammatically incorrect because a noun must be defined by a noun phrase, such as honesty is the quality of telling the truth. Maintaining grammatical consistency ensures that the definition remains structurally sound, precise, clear, and professional for readers.
