The present tense vs the closest tenses
Present — habit or general fact vs Preterite — one finished occasion
The present describes a habit, a routine or a general fact — something that happens again and again or that is true in general. The preterite reports one finished occasion in the past. Use the present when the action repeats or is still true, and the preterite when you are telling what happened once, on a specific day.
- Present — habit or general fact: {'pre_es': 'Cada día, ', 'pre_en': 'Every day, '}yo caliento la leche en el microondas — "I heat the milk in the microwave"
- Preterite — one finished occasion: {'pre_es': 'Ayer, ', 'pre_en': 'Yesterday, '}yo calenté la leche en el microondas — "I heated the milk in the microwave"
Present — now vs Imperfect — a past habit or background
The present talks about now. The imperfect talks about the past as a background — a repeated habit, an ongoing situation, something that used to happen. If you can add "used to" in English, the imperfect is usually the right choice; if it is happening now or always, use the present.
- Present — now: {}tú calientas el agua para el té — "You heat the water for the tea"
- Imperfect — a past habit or background: {}tú calentabas el agua para el té — "You used to heat the water for the tea"
Present — now or a fixed plan vs Future — what will happen
The present describes what happens now, what you do regularly, or a plan that is already fixed. The future describes what will happen later — a promise, a prediction, a plan that is not yet under way. Spanish often uses the present for near-future plans, but the future is the form for a clear statement about tomorrow.
- Present — now or a fixed plan: {'subj_es': 'Mi amigo', 'subj_en': 'My friend'}él calienta la sopa en la cacerola — "He heats the soup in the saucepan"
- Future — what will happen: {'subj_es': 'Mi amigo', 'subj_en': 'My friend'}él calentará la sopa en la cacerola — "He will heat the soup in the saucepan"
