Thanks to all ! Excellent suggestions. The translations I mostly do are government publications for general public. I prefer not to translate commonly used English words as they will be more uncomprehensable for common people anyway (Air Conditioner = बतानुकूलक ??? wow !) but the proof-reader may point out that some words have not been translated.

Here are some more words that I would like to know Nepalese versions :

version / edition
salary / wage / renumeration / perk / allowances
mobile (as in mobile phone and mobile clinic)
general outpatient clinic
water fountain
centrepiece
