Not a direct answer, but water has many names!
You tend to drop the prefix name when its a non metal reaction, so surely you say oxide not monoxide?
Water is amphiprotic-it can act as both a proton donor or a proton acceptor. Which means it can be both an acid and a base!"
Which means it can recieve a system name as a base or alkali:

The systematic acid name of water is hydroxic acid or hydroxilic acid, although these terms are rarely used.
Likewise, the systematic alkali name of water is hydrogen hydroxide -- it should be noted that water is neither an acid nor an alkali .
systematic approach is to list all the ways to group the atoms making up H-O-H, and assigning the canon.
[H2]O -> Dihydrogen Monoxide
O[H2] -> Oxygen Dihydride
[OH]H -> Hydroxic Acid, or Hydroxy Hydride (alternatively: Hydroxic Hydride)
H[OH] -> Hydrogen Hydroxide
You can also have it as an ether! So the full list of names now includes:
Dihydrogen Monoxide
Dihydrous Oxide
Dihydrogen Oxide
Dihydrogen Oxygen
Oxidized Hydrogen
Oxidized Hydronium
Oxidized Dihydronium
Hydrogen Oxide
Hydrogen Hydroxide
Hydrohydroxic acid
Hydroxic acid
Hydroxilic acid
Dihydronium Hydroxide
Dihydronium Monooxide
Dihydronium Oxygen
Dihydronium Dioxide
Hydronol
Dihydrogen ether
