"is"- it is a present continuous tense.. but they give sentence in a simple present tense.. that's what we don't use is in this case..
it's a simple present tense.. eg- she goes to house वह कर जाती है..
if it's a present continuous tense than it's come with am/is/are+verb+ing eg-she is going to home वह घर जा रहा है.. here रहा is a continuous tense(am/is/are) word.. which means we use that word instead of am/ is/ are..
Many thanks for your explanation!
I've also confronted a Hindi phrase like "go home". In that sentence there is no postposition placed after "home" while in the context of "be in the house" the postposition appears again.
It seems that some postposition may also be unnecessary due to the nature of certain verbs, at least in such phrase as "go home". Is it just an exception to this rule?
Oh yes, the rule (pattern seems more appropriate) is that postpositions are generally not used for expressing going to a place.
We are going to Delhi tomorrow. - हम कल दिल्ली जा रहे हैं।
When will you go to the temple? - आप मंदिर कब जायेंगे?
But postpositions are used when "going to" expresses movement into a region or structure.
The thieves are going into that house. - चोर उस घर में जा रहे हैं।
I'm going into the woods. - मैं जंगल में जा रहा हूँ।
The fish are going from the river into the sea. - मछलियाँ नदी से सागर में जा रही हैं।
उसका is used when what is owned is masculine. उसकी is used when it's feminine. Remember though that unlike the words his and her, उसका and उसकी do not indicate the gender of the owner.
उसका घर - His/her/its house. (House is masculine)
उसकी किताब - His/her/its book. (Book is feminine)
