Difference between "choose" and "select"

These two words are often used interchangeably and the greatest difference I can find between the two is "choose" for choosing multiple items from a set, and "select" for selecting a single item from a set. Are there other qualifiers to consider and is this singular/plural distinction on the right track?

So, really, what is the difference between the two, if any?

Select means to carefully choose; it also means to use a mouse or keystrokes to mark something on a computer screen.

In both the cases, the number of things chosen or marked does not influence which verb is used.

In addition to what you said,

According to Longman Dictionary of Contemporary English

Select is more formal than choose, and in everyday English, people usually say choose rather than select.

Also there's a homophone for choose which is chews.

According to Merriam-Webster

• choose: to have a preference for or to select freely and after consideration

• select: to choose (as by fitness or excellence) from a number or group

I checked some other sources. In all of them the difference between select and choose is not considered important. so I think maybe it's a better idea not to be fussy about it!
