worth while (worthwhile)

Short answer: worthwhile (one word) is an adjective meaning "valuable" or "worth the effort." Use worth + noun or worth + -ing when you need an object or an action (it is worth the cost; it is worth trying).

Quick answer

"Worthwhile" (one word) = adjective (valuable, beneficial). Use "worth" + noun or gerund for objects or actions.

It is worthwhile to read the report. - adjective + infinitive (formal/evaluative).
It is worth reading the report. - worth + gerund (action-focused).
Avoid: "worth while" (two words) and "worth to + verb" (wrong).

Core explanation

Adjective vs. worth + noun/gerund

"Worthwhile" describes something as valuable or beneficial: a worthwhile project; a worthwhile discussion. "Worth" needs a direct object: a noun or an -ing verb-it's about the value of that thing or action.

If you can substitute "valuable" or "beneficial," use "worthwhile."
If the phrase takes an object (cost, time) or an -ing verb, use "worth" (it is worth the effort; it is worth trying).

Spacing and spelling

When you mean the adjective, write worthwhile as one word. "Worth while" (two words) is usually incorrect. Watch idioms like "worth the while"-they keep the article "the" and behave differently.

Correct: That was a worthwhile meeting.
Incorrect: That was a worth while meeting.
Idiom: It might be worth the while to ask. (notice "the")

Hyphenation and variants

Modern English writes worthwhile without a hyphen. Forms like worth-while are archaic or decorative and should be avoided.

Wrong: worth-while
Right: worthwhile

Grammar patterns (common mistakes)

Common constructions and fixes:

It is worthwhile to + verb (adjective + infinitive).
It is worth + noun / it is worth + verb-ing (object or gerund).
