An invented language that was intended to be used internationally. It rejected all existing words and was based on the analysis and classification of ideas. Word coined by Edward P. Foster. Pronounced Roe. (This is all of the information that I can find on the subject; I will keep looking for more).

ro is the country code for Romania.
ro. is also an abbreviation for recto and rood.
.ro is used in interenet addresses to stand for Romania.
