Latin Grammar: Numbers
Regnavit autem Osuald Christianissimus rex Nordanhymbrorum novem annis, adnumerato etiam illo anno, quem et feralis impietas regis Brittonum, et apostasia demens regum Anglorum detestabilem fecerat. Siquidem, ut supra [Cap. I] docuimus, unanimo omnium consensu firmatum est, ut nomen et memoria apostatarum de catalogo regum Christianorum prorsus aboleri deberet, neque aliquis regno eorum annus adnotari. Quo completo annorum curriculo, occisus est commisso gravi praelio, ab eadem pagana gente paganoque rege Merciorum, a quo et praedecessor eius Aeduini peremptus fuerat, in loco qui lingua Anglorum nuncupatur Maserfelth, anno aetatis suae trigesimo octavo, die quinto mensis Augusti [DCXLII].
Numbers
The passage above contains several references to numbers or numerals; for example, in the first line we note that Oswald ruled nine years (novem is not to be confused with novum!) Then towards the end of the paragraph, we discover his age (trigesimo octavo) and the date (quinto mensis Augusti).
As a review of the numbers and numerals, complete the following chart, remembering that the cardinal numbers are those we use to count (one, two, three, four....) and the ordinal numbers are adjectives used to rank items: first, second, third, fourth....
