Mono-Y-Mono

No monophonic masterpiece
Sung on a monorail
In monotone with MSG
That's monosodium glutamate
I say that monotonously
A monoplane monopoly
A monomaniac with monomania
A monocle for monoculars
A monograph of monogamy
Monocetyledons- plants with single seeds
A monolith that's monogramed and monochromatic
You know the monosyllable of monotheism as fact
There is no monomial for mononucleosis
Are eggs mononuclear?
Monoxide just sounds dangerous
I have a monolingual term for mono
It's bad so please don't catch it
