People Also Ask

What does "niner" mean?

It's the standardized radio pronunciation of the number 9, stretched out so it's clearly heard over a noisy channel.

Why say "niner" instead of "nine"?

"Nine" can be confused with the German "nein" (no) or misheard as "five" over the radio, so the drawn-out "niner" keeps it distinct.

Are other numbers pronounced differently on the radio too?

Yes. The same standard gives "tree" for 3, "fower" for 4, and "fife" for 5, all to reduce confusion over the air.
