Furthest or Furthermost?

[Guest]

Happy New Year Everyone and Teacher, :D

I would like to know what is the difference between the words Furthest and Furthermost ?
I know Furthest is the superlative form of Far but I don't know about furthermost. Please tell me the usage of Furthermost.

I am waiting for your helps

Hi,

To my knowledge, Furthermost is used the same as Futherest. They are both adjective. You can also write Farthermost instead of Furthermost.

Tortoise

I think there seems to be no problem to use "furtherest" instead of furthermost. Am I correct?

"Furtherest" is not a real word. "Furthest" is standard English.

[Tofu]

Thank you, Mordant.
I won't use "furtherest," but do you often hear it used in place of "furthest"?

[Mordant]

No, Tofu. I do not. It sounds plainly wrong to the ear since "further" is already a comparative form of the original word. It's like hearing someone say "betterest."

Thank you, Mordant.
