Fordítás - Angol-Hindu - We-need-experts!

हमें विशेषज्ञ चाहिये = We need an expert. हमें विशेषजों की ज़रूरत है! would be the appropriate one with the punctuation mark included.

Thanks a lot Coldbreeze16, I edited the way you suggested to.

The singular & pleural for the word विशेषज्ञ is THE same. Thus the sentence is valid for both "We need expert" & "We need experts" The other suggested sentence is valid, too.

well...I dunno. My dictionary lists only विशेषज्ञों as plural of विशेषज्ञ. Its a small dictionary. And online dictionaries for Hindi aren't that extensive.
