rouse(rous) n.
pl:
rice(rïs)

1. A single spikelet, or "grain", from any of numerous species of the genus Oryza. (As in Oryza sativa, Oryza glaberrina, etc...)
The singular form of this word is seldom used due to the facts that:
    a)all known Oryza species produce rice in great quantities, and
    b)one rarely has occasion or necessity to isolate a rouse.
(This word-usage phenomenon is the inversion of the more familiar one with Spouse | Spice or louse | lice).

2. Proper name of the north-south road in Orlando, Florida which begins at approximately 28° 32min. 43sec.Lat. and -81° 13min. 22sec.Lon.
