Welcome to EduTurbo! Today, we’re diving into a common English grammar topic that often confuses learners: the difference between “for” and “since.” Mastering these two words can significantly improve your ability to express time accurately. Let’s break down their uses and provide some practical examples.

“For” – Duration of Time

“For” is used to indicate the duration of time – how long something has been happening. It answers the question “How long?” and can be used with all tenses.

• “For” can be used with any period of time: minutes, hours, days, weeks, months, years, decades, centuries, etc.
• It is often used with perfect tenses but can also be used with past, present, and future tenses.

“Since” – Starting Point in Time

“Since” is used to refer to the starting point of an action or event. It answers the question “Since when?” and is primarily used with perfect tenses.

Examples:

• I have lived in Melbourne since 2018.
• She has worked at the company since January.
• They have been studying English since 10 o’clock.

Usage Tips:

• “Since” is used with specific points in time: years, months, days, dates, times, events, etc.
