"To point at", "to point to" and "to point towards" are frequent phrases in dictionaries with the verb "point".
But there are also two other phrases: "to point in" and "to point into".
I'd like to find out when we can use them:
When can we use "to point in"?
When can we use "to point into"?
"To point at" — I think I kind of understand it.
But I can't understand what is the difference between the other phrases.
To figure it out, I prepared some examples:
(1) pointed into the sky
(1a) pointed to the sky
(1b) pointed towards the sky
(1c) pointed in the sky
What is the difference between (1), (1a), (1b) and (1c)?
(2) She pointed in the direction of the car park.
(2a) She pointed to the direction of the car park.
(2b) She pointed towards the direction of the car park.
(2c) She pointed into the direction of the car park.
What is the difference between (2), (2a), (2b) and (2c)?
