Well, if you haven't noticed it, you probably don't know what they are. :P
Contractions are the words such as let us, or where is, that you shorten to let's and where's, by adding an apostrophe.
Now, not many people seem to use them anyway. I can still get at what you are saying, but when people leave them out, technically the sentence makes no sense at all.
Even on the LOGICBOXES advertisement down the bottom it says:
"ITS TIME YOU CONSIDER
ICAAN ACCREDITATION"
Its is referring to something owning something, but they actually mean it is.... shocking! :o
It's even on TV now, and I don't think it's good for anything.
What do you think about this?
