How is the suffix ing added to benefit?

The suffix "-ing" is added to "benefit" to form the present participle "benefiting." This form has several uses in English:

1. As a Verb (Present Participle):

* Continuous/Progressive Tense: "They are benefiting from the new program."

* Gerund (Noun Function): "The benefiting of the community is our top priority."

* Adjective: "The benefiting program has been successful."

2. As a Noun (Gerund):

* "The benefiting from the new policy is significant."

3. As an Adjective (Present Participle):

* "The benefiting party is responsible for the costs."

Essentially, adding "-ing" changes the word "benefit" from a noun or verb into a form that can act as a verb, a noun, or an adjective, depending on its role in the sentence.
