After be used to, we use a noun or an -ing form. The meaning is quite different from    used to + infinitive. If you say that you are used to something, you mean that you know it well. You have experienced it so much that it is no longer strange to you.

be used to + noun

• I'm used to London traffic. We lived here for six years.
  
• At the beginning, I couldn't understand the Londoners, because I wasn't used to their accent.
  

We can use an -ing form after be used to, but not an infinitive.

be used to+ .. . -ing

• I'm used to driving in London now, but it was hard at the beginning. (NOT I'm used to drive ...)
  
• It was a long time before she was completely used to working with old people.
  

Get used to means 'become used to'. You'll soon get used to living in the country.

A collective noun is a noun that is singular in form but refers to a group of people or things.

Sometimes they refer to a group of specific things:-

For example:

Tables, chairs, cupboards etc. are grouped under the collective noun furniture.
Plates, saucers, cups and bowls are grouped under the collective noun crockery.

These collective nouns are often uncountable.

There are two main types of nouns: common nouns and proper nouns.

Common Nouns

Words for people, places and things are called common nouns.

These common nouns are words for  things.

ruler   chair   hammer   bicycle   truth

pen   table   saw   ship   calculator

crayons   sofa   axe   truck   television

pencil   loyalty   drill   ferry   fridge

book   lamp   ladder   train   cooker

Nouns are most often the names of people, places or things. Personal names (e.g. John and Alice) and place-names (e.g. Mumbai and Chennai) are called proper nouns; they are usually used without articles.
