Are you familiar with the phrase “here and there”?
The only difference between them is that one begins with a “t”. But obviously BOTH of them are used to describe location. You wouldn’t write “heir and their” would you ? Of course not. So everytime you need the word for location it is THERE because it’s almost the same as HERE. Both describe location.
So that leaves “their”. This is a word describing someones possessions, such as their books, their coats, etc. Etc.
To remember that “their” describes someone’s possessions, again, just drop the letter “t” and you have the word “heir” which describes one who, upon death, inherits the POSSESSIONS of another. Obviously it’s not a location word (that would be “THERE”)
An example of usage would be something like “When the parents drew up THEIR will, they left THEIR prized coin collection to THEIR firstborn son who is THEIR HEIR.
To figure out which of the two to use, all you have to do I’d pause for a second to think about which purpose it will serve. It will be either for location (HERE) or possession (HEIR). It’s one or the other. Just don’t forget to add the “t” at the beginning.
The third one is the easiest to remember since it’s the only one containing an apostrophe. The apostrophe stands for the missing letter.
The word “they’re” literally means “they are”. It can’t have any other meaning. So you can either keep things simple and always write out both words (they are). Or you can use the contraction of the two which becomes (they’re) as the apostrophe replaces the “a” in the word “are”.
So now, if you say you don’t know which spelling to use when, you can’t say that it was never explained adequately. All you have to do is remember the proper usage associated with two words which have totally different purposes. “HERE” and “HEIR” are the two key words and they’re very difficult to mix up. One is used for location and the other one
indicates possession.
So, if you can’t take a few seconds to think about the PURPOSE served by the word (location or possession) then it simply means that you can’t be bothered to exert the effort to think for a few seconds and decide.
This ain’t rocket science, you know :)
But at least you can never again say that nobody gave you a clear explanation with included memory association word cues. (HERE and HEIR)
The ball is in your court now.
