SOME and ANY - what is the difference?

SOME and ANY are known as quantifiers, i.e. when we don't specify the amount of something, we use these words. 

SOME and ANY are used for countable and uncountable nouns.

SOME usually implies talking about a specific thing or person. 

For eg.:	I had some oranges for breakfast.
	Some of the chapters in this book are incomplete.
	Some of you would be selected for the school’s volleyball team.

SOME is also used when offering someone something.

For eg.:	Would you like some tea?
	I insist you have some of my home-made pies.
	Do you need some help with that luggage?

ANY is used when talking about unspecified things. It is mostly used in negative sentences and questions.

For eg.:	I haven’t had anything to eat since morning.
	Anything is possible.
	I don’t know anything about marine animals.
	Do you have any floral scarves I could borrow?
	Is there any way I could get hotel reservations for tonight?

For some sentences, SOME and ANY both can be used, depending upon the intention of the speaker.

For eg.:	Would you like to have something?	Would you like to have anything?
	Do you have some cough syrup?	Do you have any cough syrup?
	Is there some orange juice left?	Is there any orange juice left?
	I have to buy this sweater somehow.	I have to buy this sweater anyhow.
