Is tires = fatigue a word?

Apparently you didn’t look in the right dictionary.

To be fair, a few other dictionaries also did not have “tires”, only tire and tired.

Glad to get that cleared up.

I was writing a reddit post and was concerned about car tire jokes if I used tires. I ended up substituting a different word.

Someone mentioned above that questioning our spelling can lead to confusion.

I’ve been racking my brain trying to think of an exception but I don’t think there is one. This is universal.

Sometimes the spelling changes, so for example “try” becomes “tries”, but there is still an “s”.

If you have a regular verb, there will be a valid form with an “s” at the end.

That phrase tires me out.

You know why bicycles fall over?

They’re two tired.

(Well, an exception would be an irregular verb…)

But I think you’re right, all the irregular verbs end in “s” too, except modal verbs which is cheating.

thou wost
he/she/it wot

they wit

That’s why we voted Middle English out of the language in the by-election of 1678.
