To, Too, Two?
Grammar is a funny thing, especially in the English language. When you are a native speaker of a language, it can be hard to completely understand the grammar of the said language, mainly because the way in which you learned it was very much through cultural understandings.
So when you are presented with three different ways of spelling and using a word, it can be confusing for non-native speakers. For you, it is easy to understand when and where to place the correct word, but for someone else, it can be very confusing.
