The present tense is used to describe actions, situations, or conditions that are happening now or are generally true. It indicates an action that is ongoing or a state that currently exists. Here are some key points about the present tense:

Subject-Verb Agreement: In the present tense, the verb form must agree with the subject. This means that for third-person singular subjects (he, she, it, or a singular noun), the verb usually takes an -s or -es ending.

Time References: The present tense can be used to refer to habitual actions, routines, general facts, or fixed arrangements in the future.

Signal Words: Some common signal words that indicate the present tense include "always," "usually," "often," "sometimes," "every day/week," and "right now."

Examples:

Remember that while the present tense is primarily used to describe current situations, it can also be used to discuss future events when they are part of a fixed schedule or plan.
