Obviously, different languages use contractions differently. So I was wondering if you could answer a few questions about languages other than these four that you are familiar with: Are there common contractions in your language(s)? Do they tend to have a quality (negative, positive, neutral) to them? Is there a special symbol used to show that these words are contracted? Is this symbol always used or, like German and French, is it used for some instances and not others (or am I wrong and English does this, too)?
Thanks in advance!
