WHILE और WHEREAS (EXPLAINED IN HINDI)

1. ‘While’ का use उन कथनों को व्यक्त करने के लिए किया जाता है जो किसी time से सम्बंधित होते हैं या कोई विरोधाभाष (contrast) दिखाने के लिए होते हैं जबकि ‘whereas’ का use सिर्फ विरोधाभाष दिखाने के लिए ही होता है; time के लिए नहीं; जैसे 

Preeti liked tea while Sneha preferred coffee.
= Preeti liked tea whereas Sneha preferred coffee.

[ये दोनों ही वाक्यों के अर्थ बिल्कुल एक ही हैं, और प्रीति और सनेहा की पसंदों के बीच विरोधाभाष दिखा रहे हैं.]

अन्य उदाहरण जहाँ ‘while’ और ‘whereas’ में से किसी का भी use किया जा सकता है:

a) While/Whereas I like all types of fish, my girlfriend always chooses meat dishes when we go out to eat. (विरोधाभाष)
b) Some married couples argue all time, while/whereas others never do. (विरोधाभाष)

INCORRECT: Preeti did the ironing whereas Sneha swept the floor.
CORRECT: Preeti did the ironing while Sneha swept the floor.

[ये वाक्य हमें बता रहा है कि प्रीति और सनेहा दोनों ने ironing और sweeping दोनों काम एक ही समय किये हैं. क्योंकि time के लिए ‘whereas’ का use नहीं होता; आप यहाँ ‘whereas’ का use नहीं कर सकते. .]

अन्य उदाहरण जहाँ ‘whereas’ का use सम्भव नहीं है:

a) I listened to music while Reema cleaned the house. (समय)
b) While I was watching a movie on the T.V., the children were playing in the other room. (समय)
c) Can you wait in the car while I wear dress to get ready? (समय)
d) While Geeta was dancing, her brother was reading. (समय)

NOTE-I: While अथवा Whilst?

Conjunctions के रूप में ‘while’ और ‘whilst’ का अर्थ एक ही होता है.

Would you like something to eat while we’re waiting?
=  Would you like something to eat whilst we’re waiting?

NOTE-II: While अथवा When?

When और While दोनों का अर्थ एक समान हो सकता है; परन्तु जब कोई निश्चित समय (point in time) दे रखा हो तो सिर्फ ‘when’ का use  ही किया जा सकता है ; ‘while’ का नहीं; e.g.

तुलना कीजिये:
The phone rang while we were having dinner.
= The phone rang when we were having dinner.

[Here While/When = जब कुछ हुआ हो उस समय के दौरान]

INCORRECT: While the phone rang, she answered it immediately.
CORRECT: When the phone rang, she answered it immediately.

[फोन की घंटी एक निश्चित समय पर बजी; अतः यहाँ ‘while’ का use संभव नहीं है.]

INCORRECT: Always keep some change with you. It’s useful while buying a bus ticket.
CORRECT: Always keep some change with you. It’s useful when buying a bus ticket.

WHILE Vs WHEREAS (EXPLAINED IN ENGLISH)

We use ‘while’ for expressions of time or to show a contrast, but we use ‘whereas’ only to show a contrast for times; e.g.

Preeti liked tea while Sneha preferred coffee.
= Preeti liked tea whereas Sneha preferred coffee.

[These two sentences are identical in meaning, and show a contrast.]

More examples where you can use either ‘while’ or ‘whereas’:

a) While/Whereas I like all types of fish, my girlfriend always chooses meat dishes when we go out to eat.
b) Some married couples argue all time, while/whereas others never do.

INCORRECT: Preeti did the ironing whereas Sneha swept the floor.
CORRECT: Preeti did the ironing while Sneha swept the floor.

[This sentence tells us that Preeti and Sneha did these tasks simultaneously. There is no suggestion of contrast.]

More examples where you cannot use ‘whereas’:

a) I listened to music while Reema cleaned the house.
b) While I was watching a movie on the T.V., the children were playing in the other room.
c) Can you wait in the car while I wear dress to get ready?
d) While Geeta was dancing, her brother was reading.

NOTE-I: While or Whilst?

‘While’ and ‘Whilst’ mean the same when we use them as conjunctions. They both mean ‘during the time that something else happens’, or ‘in contrast with something else’. While is much more common than whilst, and whilst sounds more formal:

Would you like something to eat while we’re waiting?
=  Would you like something to eat whilst we’re waiting?

NOTE-II: While or When?

‘When’ can mean the same as ‘While’, but when a point in time is given we can only use ‘when’; not ‘while’; e.g.

Compare:
The phone rang while we were having dinner.
= The phone rang when we were having dinner.

[Here While/When = during the time something happens

INCORRECT: While the phone rang, she answered it immediately.
CORRECT: When the phone rang, she answered it immediately.

[THE PHONE RANG at a particular time; therefore you can’t use ‘while’ here.]

INCORRECT: Always keep some change with you. It’s useful while buying a bus ticket.
CORRECT: Always keep some change with you. It’s useful when buying a bus ticket.
