Google ‘Define’
Most people use Google to search for websites, images, and so on, however some people use Google to define / look up the meaning of words.
For example, if I wanted to know the meaning of “Beach” I would type “define:beach” without the quote into Google and it will return something like “an area of sand sloping down to the water of a sea or lake” depending on what you define many other things can show up.
I’ve used define many times and its great, but to be honest it hasn’t always given me what I wanted.
