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 Latin word order The word order of classical Latin is relatively free. Subject, Object, and Verb can come in any order; adjectives and possessives can go before or after their noun, and so on. A commonly found feature of Latin is hyperbaton, in which a phrase is split up by other words, e.g. "Sextus est Tarquinius" "it is Sextus Tarquinius". A complicating factor in Latin word order is that there are variations between the style of different authors, and also between different genres of writing; in Caesar's historical writing the verb is much more likely to come at the end
