We use the present continuous tense (also called the present progressive) to describe a temporary action that is currently occurring (e.g., “I am gardening right now”) or sometimes a planned future event (e.g., “We are travelling to Greece this summer”).
It’s used differently from the simple present, which instead indicates a habit (e.g., “I garden on Tuesdays”), a general truth (e.g., “Bears hibernate in the winter”), or a fixed situation or state (e.g., “She speaks French and German”).
