Question

“be known to" and "be known for"difference
Today I lean that two words."be known to "and "be known for":
the example is :
The singer is known to people in the world.
if i want use "known for" that the sentence is 
He is know for the singer in the world. 
right?

Answer

"Known to" means that someone or something is known to a specific group:

i.e. This snake is the deadliest one known to man!

**Here, the snake is one of the deadliest known to mankind (specific group)

"Known for" means that someone/something is recognized for some special trait or quality:

i.e. The chef is known for his delicious lobster.

**The chef is recognized by other people for his lobster (it is very delicious, which makes it a special feature)

Answer

Your sentence would not be right because "known for" always has to be followed by a description.

"He is known for playing the piano."
"Brad Pitt is known for his acting."

Does that help?

Answer

be known for something means that you're known by a lot of people (famous in other words) because of that something.

So "He is know for the singer in the world" is incorrect but:

"He is known for being a singer" "He is known for signing" "He is known for his songs" are all correct
