1. Understanding Tenses

Tenses are primarily categorized into three main time frames: past, present, and future. Each of these categories can be further divided into four aspects: simple, continuous (progressive), perfect, and perfect continuous. This structure allows for a comprehensive understanding of how actions relate to time.

1.1 The Three Main Time Frames

• Past Tense: Describes actions or states that occurred before the present moment.
• Present Tense: Describes actions or states that are currently happening or are habitual.
• Future Tense: Describes actions or states that will occur after the present moment.
