Since” and “for” talk about time from the past till now, so we cannot use the simple present or present continuous here. When an action started in the past and is still continuing, English uses the 👉 present perfect continuous tense. So we say: ✔ He has been living with his parents for 5 years. ✔ She has been working here since 2020. Also remember: • for → duration (for 5 years) • since → starting point (since 2020) Simple rule: 👉 Since/for action continuing till now = has/have been verb-ing #
