Final Thoughts
The difference between world-class and world class is small but important. The hyphen is not decorative; it signals that two words act as one adjective before a noun. After a linking verb, the phrase stands independently and does not need a hyphen.
This rule strengthens clarity, improves readability, and reflects professional attention to detail. Whenever you use the phrase, simply check its position in the sentence. If it modifies a noun directly, hyphenate it. If it follows a verb, leave it open.
Mastering this distinction ensures your writing remains polished, accurate, and consistent across academic, business, and editorial contexts.
