The Origin of Thier, Their, and There

The words their and there have different origins in English:

• Their comes from Old Norse “þeirra”, meaning belonging to them.
• There comes from Old English “þǣr”, meaning in that place.

Thier has no historical basis. It is simply a modern typo caused by misplacing vowels. Its popularity comes from hearing the word “their” and incorrectly spelling it i before e except after c, which does not apply here.
