Something that really annoys me these days is the way people pronounce etc. Some people pronounce it eK-setera.
This is absolutely incorrect, the second letter is a T for a reason, it's pronounced eT-setera.
I honestly don't know how people can pronounce it the incorrect way; I mean the sea comes after that T, is it that hard to pronounce the T???
A teacher I knew even emphasised the k sound when pronouncing the incorrect way.
It really gets on my nerves, as does all incorrect grammar - it's really not that hard to learn how to speak properly and to use words properly.
Come on people, learn to speak English properly.
