What is the use of gerund? What words does it usually modify?

As the name suggests, gerunds are words that form a noun with verb + ing, such as

go + ing = going

sing + ing = singing

< p>Since they are nouns, they certainly do not modify any words.

Their usage is generally the same as common nouns, please see the example:

Going home is always something to look forward to.

Singing in the rain can be quite an exhilarating experience.

Smoking is bad for your health.
