A sparse lexical neighborhood is characterized by a low density of words that are similar in phonological structure. This means that within this type of neighborhood, there are fewer similar words that sound alike or share similar phonetic characteristics.

The choice highlighting the large number of synonyms is correct because, in a sparse lexical neighborhood, the absence of closely related words or synonyms indicates a unique or less crowded group of terms. In contrast, a rich lexical neighborhood would include many synonyms or phonetically similar words.

In addition, the characteristics of a sparse lexical neighborhood—such as fewer similar words, higher ease of recognition, and basic familiarity with terms—are all inherently linked to having fewer competing words that may confuse or complicate the recognition process. The fewer similar words present enhance the ease of recognition, as it becomes clearer which term is being referred to, and there tends to be a basic familiarity with the limited vocabulary available.
