What is the literal meaning of a word referred to as?

The literal meaning of a word is referred to as "denotation." This term specifically describes the primary, explicit meaning of a word as it is defined in a dictionary, without any emotional associations or secondary meanings that might come into play. In essence, denotation provides the straightforward, direct meaning of a word, making it foundational for understanding language in its most basic form.

The other terms present in the options reflect different aspects of language. "Connotation" refers to the emotional or associative meanings that a word carries beyond its literal definition, often shaped by cultural or personal experiences. "Implication" involves something that is suggested or inferred but not directly stated. "Innuendo" refers to an indirect or subtle reference, especially one with derogatory implications. While these terms are relevant in discussions of language and meaning, they do not describe the straightforward, dictionary-based definition that denotation provides.
