Since और For का सही इस्तेमाल: English Sentences और Examples

Since और for दोनों time बताने के लिए use होते हैं, लेकिन इनका मतलब अलग है।

• since = किसी starting point से
• for = किसी duration / period के लिए

अगर आप यह याद रख लें, तो ज़्यादातर sentences में गलती नहीं होगी।

Since कब use करें?

जब आपको बताना हो कि कोई काम कब से चल रहा है, तब since use करें। इसके बाद कोई exact point आता है, जैसे:

• 2019
• Monday
• सुबह 8 बजे
• yesterday
• last year

Examples

• I have lived here since 2019.
• She has worked here since Monday.
• We have known each other since childhood.
• He has been sick since yesterday.
• The shop has been closed since 10 a.m.

इन sentences में since के बाद starting point दिया गया है।

For कब use करें?

जब आपको बताना हो कि कोई काम कितने समय से चल रहा है, तब for use करें। इसके बाद time period आता है, जैसे:

• two hours
• three days
• five years
• a week
• a long time

Examples

• I have lived here for five years.
• She has worked here for two months.
• We have waited for an hour.
• He has studied English for a long time.
• They have been friends for many years.

इन sentences में for के बाद duration दिया गया है।

Since और For का सबसे आसान फर्क

एक simple सवाल पूछिए:

• कब से? → since
• कितने समय से? → for

Compare करें

• I have lived here since 2018.

= मैं 2018 से यहाँ रह रहा हूँ।

• I have lived here for 10 years.

= मैं 10 साल से यहाँ रह रहा हूँ।

दोनों sentences सही हैं, लेकिन information अलग है।

Since और For के साथ कौन सा tense आता है?

Since और for अक्सर present perfect और present perfect continuous tense में आते हैं।

Present perfect

• I have known him since 2020.
• She has worked here for three years.

Present perfect continuous

• I have been learning English since January.
• He has been studying for three hours.

अगर sentence में काम अभी भी चल रहा है, तो ये tenses बहुत common हैं।
