curious-- i just heard fortnight on TV new this week-- a national broadcast--I thought it strange– its not that most of don't know the meaning of the word–wait let me back track many might be closer. But its never used.

just as we know what you are talking about when you say lift or lorry, but we take our elevators and truck stuff about .

the only time I have seen sennight is in Patterns by Amy Lowell– and I had to look it up! Aside from there, the dictionary I looked it up, I have never seen it in print, anywhere else.

what I like about fortnight and suspect it hold true for sennight, is it can be a fortnight Wednesday–say from December 6 to December 20. Where as a week starts with Sunday. So sennight is seven days–but a week is from Sunday to Sunday? Does that make sense? (Or is it just my personal interpretation?)
