On 14 Jan 2010, at 04:03, ---- LANGUAGE > > Latin: Virus (= Illness) singular Viruses plural There is a body of opinion which will disagree with you, bearing in mind that few people study Latin in schools now. So far too many people use words like "forums" and "stadiums", when "fora" and "stadia" are more correct plurals; and worst of all is the totally incorrect use of the word "decimation" which really means "reduce by one tenth" and not "reduce to one tenth". Apologies for the off-topic, but I spent 5 years on school Latin - ah school days and the joys of P.V. Maro ! Anyway back to my Polaroid experiments, sadly too few in the awful UK weather we are having - a finding so far is that outdated film is usable for a surprisingly long time. dan.
