Learn English: how to understand differences between similar words

What is the difference between “discreet” and “discrete”; “color” and “colour”; “who” and “whom”?

These questions trouble everyone who speaks English, including those for whom it is their mother tongue.

My tip is to search on the Internet using Google or a similar site like this:

discreet vs discrete

color vs colour

who vs whom

That is how English websites entitle pages which explain such confusion. Type “[word] vs [similar word]” and you will always find an explanation. Please try it.
