Compound nouns are made up of two or more words that act as a single unit. They can be:
* Open compound nouns: written as two separate words (e.g., high school, post office)
* Closed compound nouns: written as one word (e.g., keyboard, textbook)
* Hyphenated compound nouns: written with a hyphen (e.g., walk-through, well-being, self-esteem)
"Walk-through" is a hyphenated compound noun because it describes a specific type of process or event. It refers to a detailed explanation or guided tour, often used in situations like:
* Software development: A developer walks a client through the features and functionality of a new application.
* Construction: An architect leads a client through the design plans of a building.
* Theater: An actor rehearses a scene with the director.
Hyphenation helps to clarify the meaning and distinguish the compound noun from individual words. In this case, "walk through" could be interpreted as simply walking through a space, while "walk-through" specifically refers to a guided tour or explanation.
