is the Old English root of “sickness”. I’ve been seoc for a week, with a nasty head and chest cold, and to keep from blaming the little kids I work with for poisoning me (on my first day at the school!) I wrote a limerick:
Three year old children do not,
clean off their faces of snot,
nor wash their hands much,
to this whisky I’ll clutch,
having caught all their germs in one shot.
