Question

difference between distinguish and discern ?

Answer 1

Discern is just to notice something. To distinguish is perhaps to discern differences. 

Discern - means to notice, but is rarely used in that form unless in very formal setting. 'Discernible' is more common, eg. 'He had a discernible accent.'

Distinguish - means to mark the difference/s between one thing and another/others. Eg. I can distinguish Emily from her twin sister because Emily has shorter hair.

hopefully this helps

Answer 2

Discern:To detect with the senses, especially with the eyes.

Distinguish:To see someone or something as different from others.
