🧠 Explanation:
- Single spacing in MS Word typically refers to the default line spacing used in a document.
- Historically, single spacing equals **12-point** line spacing, which matches the size of a standard 12pt font.
- This measurement ensures that each line of text is spaced for clear readability without extra white space.
- Microsoft Word may visually adjust this slightly with modern fonts, but technically, it still aligns with the 12-point baseline rule.
