‘Hajur’ is four different words wearing one coat

If you learn one Nepali word, learn this one. It is not a word so much as a setting.

• As “you”. The respectful second person. Using timi where hajur was expected is the single fastest way to be thought rude by someone who will never tell you.
• As “yes?” Someone calls your name from another room. You do not say yes. You say hajur, rising slightly, and it means “I heard you, go on”.
• As “sorry, what?” The same word, same rise, used when you did not catch something. Context does all the work and does it perfectly.
• As “hello”. Answering the phone. Not namaste — hajur.
• As a full sentence of agreement, repeated: hajur, hajur. Yes, yes, of course, absolutely.

Four completely different jobs, one word, and no Nepali speaker has ever been confused about which was meant. The tone carries all of it — which is why the word is almost impossible to use correctly from a phrasebook and almost impossible to get wrong after a month of hearing it.
