House: A building in which people live or reside/a building for any purpose like worshipping, business deals etc.
Home: A place where people settle down, a place which gives a feeling of comfort.
The basic difference between a Home and a house is that a home gives you a feeling of security and peace; a place which gives you a feeling of belonging.
A house maybe termed as a building/a building where meetings take place etc.
eg: I am going Home during my holidays....
-- We are planning to build a house.
-- Your home is so comfortable.
-- That house (building) is so huge!!
2) Big: means large, full-size.
Large: Huge, fat, bulky, hefty, outsized.
Big also means large but large has other meanings like fat, over sized etc.
Eg: Big: He has a big house.
ii) Large: He has a large size or his size is large.
EG: Her eyes grew big/large with fear.
The quantity of food that he intook was quite large (meaning he ate a lot, you can't say big here).
Hope this clarifies.....
