The phrase ‘am running’ is in the present continuous tense.
This tense is used to describe actions that are currently happening or ongoing. It is formed using the present tense of the verb ‘to be’ (in this case, ‘am’) followed by the present participle of the main verb (which is ‘running’).
For example, if someone says, ‘I am running,’ it indicates that the action of running is taking place at this very moment. This tense is commonly used in everyday conversation to convey that something is happening now, making it a crucial part of English grammar.
