Since vs. For: Know the Difference
By Shumaila Saeed || Published on January 24, 2024
Since is used to indicate the starting point of actions or events in time, while For is used to specify the duration of actions or events.
Key Differences
Since is typically employed to refer to a specific point in time from which an action, event, or condition began and continues to the present. For example, "Since 2010, the company has grown significantly." In contrast, For indicates the duration of time that something has been happening. For instance, "For ten years, the company has been growing."

Usage in Sentences: When using Since, it specifies the commencement time of an action or state and is often used with perfect tenses. "I have lived here since January." For, however, denotes the length of time an action has continued and can be used with various tenses. "I have lived here for three months."

Temporal Contexts: Since is fitting when the focus is on the starting point of actions or situations. "She has been teaching at the university since last fall." Whereas For is suitable when emphasizing the duration or amount of time of an ongoing situation or action. "She has taught at the university for over a year."
