I hate the word ‘orientate’.
I used to think this word was one made up by illiterate morons, and was dismayed when I checked a dictionary to find it is listed as a real word. It means exactly the same thing as ‘orient’, which is a perfectly good word that DIDN’T NEED THREE MORE LETTERS ADDING.
Whenever I hear people using this bastardisation, I want to throttle them. Especially if they use it to define OOP as ‘Object Orientated Programming’, because that actually is wrong.
