Which of the following defines the specific dictionary definition for a word?

The term that accurately describes the specific dictionary definition of a word is denotation. Denotation refers to the literal meaning of a word or the objective meaning that is explicitly defined in a dictionary. This is the definition that most people would agree upon without the influence of personal attitudes or emotional associations.

In contrast, connotation refers to the emotional or cultural associations that a word carries in addition to its denotative meaning. This encompasses the feelings and ideas that a particular word evokes, which can vary depending on context, culture, or personal experience.

An idiom is a phrase where the meaning cannot be understood from the literal definitions of the respective words. For example, "kick the bucket" is an idiom meaning to die, which is not evident from the individual words.

A technical term is a word or phrase that has a specific meaning in a particular field or profession, such as "photosynthesis" in biology. While these terms have precise definitions within their contexts, they are not necessarily the same as the standard dictionary definitions applicable to the more general use of the word.

Therefore, denotation is the correct choice because it reflects the fundamental, objective meaning of a word as found in a dictionary.
