What does verb ending-ing mean?

Answer 1

In English, the suffix -ing denotes a continuous tense. It can be present continuous (which is more common) or past continuous.

For example:

Present continuous

Bob is running

Past continuous

Bob was running

The former is used when the action is still happening. In this case, Bob is running as I am typing this.

The latter is used when Bob was running continuously before, but has stopped.

Answer 2

A verb ending in "-ing" typically indicates the present participle form of the verb, showing that the action is ongoing or continuous. It can also be used as a gerund, where the verb functions as a noun in the sentence.
