What is an example of lexical ambiguity?

Lexical ambiguity occurs when a word has multiple meanings, leading to confusion or uncertainty about which meaning is intended in a given context. The example of the word "light" perfectly illustrates this concept, as it can refer to illumination, something that is not heavy, or various other interpretations depending on the context in which it is used. By having multiple meanings, "light" exemplifies how a single term can generate different interpretations, making it a clear instance of lexical ambiguity.

The other options address different linguistic phenomena. A word that is used incorrectly in a sentence speaks to improper usage rather than multiple meanings. Words that sound similar but have different meanings refer to phonetic ambiguity or homophones, which focus on sound rather than meaning. Complex sentences that confuse the reader involve syntactical structure rather than the ambiguity of individual words. These distinctions highlight why the specific example of a word like "light" having various meanings is a quintessential case of lexical ambiguity.
