One of the most difficult things even for native speakers of English to learn is the correct use of contractions. To this day when I type
it and want to follow it with
s I have to spend a fraction of a second reading the sentence out loud to see if
it is will fit. Then there's the question of where the apostrophe belongs. Why isn't it
is'nt?1 What makes all this worse is that the first time you use
its instead of
it's people start sending you links explaining how to write properly.
I can think of two reasons to still use contractions:
It's slightly faster to write. (But only if you don't have to think about proper usage.)
We use contractions in verbal communication and contractions reflect the sound of our speech.
Wh'tcha yall rec'n?
