Verbal Reasoning — Classification (Always/essential component): Determine what is always associated with a “phrase”. Consider linguistic essentials of a phrase as a naming/wording unit, not external reference tools or visual effects. Choose the option that best matches what a phrase must involve.

Concept/Approach
In grammar/semantics, a phrase is a small syntactic unit used to name or denote something (a unit of wording). Among the given options, nomenclature (the act/system of naming/wording) is the most directly connected to what a phrase inherently provides.

Option Analysis

• Nomenclature — aligns with the idea that a phrase is a unit of wording/naming. Correct.
• Manifestation — too broad.
• Pictorial effect — visual, not linguistic.
• Glossary — an external list of terms; a phrase does not always reside in a glossary.

Final Answer
Nomenclature.
