· The phrase "since ten years" is incorrect. "Since" is used for a specific point in time, whereas "for" is used for a period of time like ten years.
· The correct phrase is "for ten years."
· Correct sentence: "Neeta served as President of the Oshinara club for ten years."
· Rule:
· Use "since" with specific years or points in time (e.g., since 2012, since morning).
· Use "for" with durations (e.g., for 10 years, for two hours).
Example :I have been living here for five years.I have been living here since 2018.
