Can we use the word Worth with To infinitives as worth to read. Would you please explain why is improper usage?

You're right, "worth to read" is incorrect grammar. While it sounds intuitive, the word "worth" in this context takes a gerund (verb ending in -ing), not an infinitive.

Here's why:

* "Worth" is an adjective: It describes something as valuable or deserving of a particular action.

* Gerunds act as nouns: They represent the action itself.

* Infinitives express purpose or potential: They are used to describe the intended action or possibility.

Correct Usage:

* "Worth reading" - Here, "reading" is a gerund, acting as the noun object of the adjective "worth." It means the book/article is valuable for the act of reading.

* "Worthy of being read" - This emphasizes the value or quality of the item making it worth reading.

Incorrect Usage:

* "Worth to read" - This is grammatically incorrect because "to read" is an infinitive, expressing potential action, not the action itself.

In summary: "Worth" functions as an adjective and requires a gerund (verb ending in -ing) to describe the action it deems valuable.
