The sun bask on my hand. (The sun was shine on my hand and i feel it very hot)
Please put the washing out and bask in the sun. (To put the clothes under the sun to try the clothes)
How to say in correct way?
I am not a teacher.
We don't use bask in this way.
The sun doesn't bask on you, you bask in it.
It is for relaxation and enjoyment so, "Please put the washing out and bask in the sun." would make sense if someone was asking you to put the washing out and then inviting you to bask in the sun. The clothes don't bask in the sun, they are dried by it.
