how can i know the gender of the things book grass ....
i m not english is more dificult for me learn for this reason i m spanish
In general, there is no way to know the gender of words other than by encountering them again and again (I assume this is the case in Spanish too?). I would suggest that any time you come across a new noun, you learn it along with its gender.
Should be पिता not पापा no?
पिता, बाप, पापा are all words for father. पिता is formal and बाप is informal. पापा is like Dad/Daddy in that it's more common as a term of address.
Why is this in the plural "के" and "लंबे"? Does "ke" count as a postposition and therefore is this the oblique case?
"के" and "लंबे" are indeed plural forms and are used because पिता usually exhibits, as do माता, दादा, गुरु, etc., what's called honorific pluralization.
Ahhh. Thank you! That does make sense. Are मां, नानी, दादी etc also pluralised for this reason or is it a gender-specific thing?
You're welcome. :) Those words, too, are pluralised for the same reason.
Awesome, this is really helpful, thanks!
Glad to help.
how many father has julia one father chota not chote explain me this please
You treat words referring to people older than you (like पिता) as plural as a show of respect.
Does Julia have more than one father? Is that the reason it is in the plural?
