Since vs For — #learnenglish #britishenglish #english #languagelearning #englishtips

In English grammar, 'since' is used to indicate a starting point in time (when something began), while 'for' is used to indicate duration (how long something has been happening). For example, 'I've lived here since 2020' (starting point) is correct, while 'I've lived here for 5 years' (duration) is correct; however, 'I've worked here since 3 years' is incorrect because 'since' should not be followed by a duration.
