Key ideas in English Grammar for Clarity
- Present perfect ties a past event directly to a current unfinished result.
- Simple past isolates an event inside a closed, completed time window.
- Choosing 'have lost' tells listeners the key is still missing right now.
- Past continuous sets a continuous backdrop underway at a specific moment.
- Simple past introduces the sharp event that interrupts an ongoing action.
- Using continuous for both clauses incorrectly implies two parallel scenes.
- 'Would' only expresses repeated actions or routines, never static states.
- 'Used to' works for both past states like living somewhere and repeated habits.
- Stative verbs like 'live', 'be', or 'know' require 'used to' for past situations.
- 'Going to' expresses plans already made or predictions based on visible evidence.
- 'Will' expresses spontaneous decisions formed in the very moment of speaking.
- Contextual cues like physical proof or prior booking dictate future forms.
- Present simple describes future events governed by public calendars and timetables.
- Timetable present simple signals external authority rather than personal choice.
- Personal intentions use 'going to' or present continuous, not present simple.
- 'Must' expresses near-certain deduction based on strong evidence
