Coronavirus Coronavirus Coronaviruses are species of virus belonging to the subfamily "Coronavirinae" in the family "Coronaviridae", in the order Nidovirales. Coronaviruses are enveloped viruses with a positive-sense single-stranded RNA genome and with a nucleocapsid of helical symmetry. The genomic size of coronaviruses ranges from approximately 26 to 32 kilobases, the largest for an RNA virus. The name "coronavirus" is derived from the Latin "corona", meaning crown or halo, and refers to the characteristic appearance of virions under electron microscopy (E.M.) with a fringe of large, bulbous surface projections creating an image reminiscent of a royal crown or of the solar corona.
Latin word order nuances of meaning and emphasis. As the authors of "Latin Word Order", Devine and Stephens, put it: "Word order is not a subject which anyone reading Latin can afford to ignore. ... Reading a paragraph of Latin without attention to word order entails losing access to a whole dimension of meaning." One important advantage of studying word order in Latin is that it helps the reader to understand the author's meaning more clearly. Thus for example "complosit Trimalchio manus" doesn't merely mean "Trimalchio clapped his hands", but the initial verb implies a sudden action: "Trimalchio suddenly clapped his hands". In
