Passim in the Steamship challenge game

[Jacki]

Missed this common word - passim. Never ever heard of it! Means occasionally, here and there.
Hopefully I'll know it when it comes up next time - in a passim way!

[anona]

I didn't play that game. I know passim and would have accepted it without a blink had I read it in an article.  But I'd probably not have thought to play it except in desperation because I had forgotten that it had passed into English as ergo has. I've not met it for years.

[mkenuk]

I was one of the 20 who played it;
I don't think I've ever seen it except in a footnote in a textbook.
I was a bit surprised it was common especially as a similar word idem which also inhabits footnotes and which appears quite frequently in Chi games is classed as 'uncommon'
