why don't we need to put the word ek, for a?
Most of the times articles are not compulsory in Hindi. However you shouldn't be marked wrong if you choose to use it.
Thanks for all the great comments you have left emrys29.
I think that since usually Hindi speakers don't insert the articles, it is best to teach us not to do that.
Why do they put the adjective before the noun here??? I've seen it after the noun several times as well. Is there a rule??
It changes the meaning when you move the adjective. After the noun would (I think) mean, " That man is short." वह आदमी छोटा है ।
वह आदमी छोटा है. This answer is also correct.
Is the term "chota" a polite word to use?
Ek kidhar hai?
