What is the difference between “since” and “for”? Does “since” indicate the starting point of an action, while “for” shows the duration? How do these adverbs modify the meaning of a sentence when describing the length of time something has occurred, providing clear context for the timeline of events?
“Since” and “for” are both used to express the duration of an action or state, but they are used in different contexts.
1. “Since” is used to indicate a specific point in time when an action started.
Example: “I have lived in this city since 2010.” (The action of living in the city started in 2010.)
2. “For” is used to indicate the duration of an action or state.
Example: “I have lived in this city for 10 years.” (The action of living in the city has lasted for 10 years.)
In summary, “since” is used to specify the starting point of an action, while “for” is used to express the duration of that action. Both adverbs help provide a clear timeline of events in a sentence.
