AI Overview
Yes, walkthrough can be hyphenated as walk-through, but it is more commonly written as a single, closed compound word, walkthrough. While the hyphenated form is acceptable, the single-word version is preferred in modern English.
Here's a breakdown:

    Walkthrough: (one word) is the most common and widely accepted spelling.
    Walk-through: (hyphenated) is also a valid and understandable option, especially in certain contexts like technical writing or when referring to a specific type of walkthrough (like a rehearsal).
    Walk through: (two words, open form) is generally not used as a noun referring to a tutorial or explanation.
