Best practice
Always double-check your pronoun usage; "their" indicates possession, while "there" indicates existence or location.
Common error
Avoid using "their was" by remembering that "their" shows ownership. Use "there was" to indicate something existed, and "they're" is a contraction of "they are".

Ludwig's WRAP-UP
The phrase "their was" is a common grammatical error where the possessive pronoun "their" is incorrectly used instead of the adverb "there". As Ludwig AI clearly points out, the correct usage depends on the intended meaning: "there was" indicates existence, while "they were" is the correct plural form. Despite its frequent occurrence, especially in News & Media and Academia, "their was" should be avoided in favor of grammatically sound alternatives to maintain clarity and credibility in writing.

FAQs
What's the difference between "their was", "there was", and "they're was"?
"Their was" is grammatically incorrect. "There was" indicates the existence of something, while "they're was" is also incorrect. "They're" is a contraction of "they are" and cannot be followed by "was".
When should I use "there was" instead of "their was"?
You should always use "there was" to indicate the existence of something in the past. "Their was" is never grammatically correct.
How can I avoid confusing "their" and "there" in my writing?
Remember that "their" indicates possession (belonging to them), while "there" indicates a place or existence. If you mean to say something existed, use "there was".
Is "their were" ever correct?
"Their were" is never correct. "Their" indicates possession and cannot be used with "were". The correct phrase indicating plural existence in the past is "they were" or "there were".
