Lesser-known Greek letters: the letter "Stigma".

Edit: also funny:

"Lollipop Koppa"

I've seen those! They hang around outside primary schools in the morning and afternoon and give road safety lessons!

("koppa" = "copper"... oh never mind. Rule 2 of humour: if it has to be explained it was crap to begin with.)

Hyuk hyuk!

<-- Stigmata

[markadm.livejournal.com]

equals the last 's', yes?

It's all horrendously confusing. Originally a 'sigma-tau ligature' (I'm assuming this means it was a 'st' sound; hence the name), then borrowed as a name for the cursive form of 'digamma' (a 'w' sound) because they looked kinda the same. Then borrowed again as a name for the final sigma in modern Greek.

Modern unicode has a 'final sigma' which it notes is also known as 'stigma', an actual 'stigma' and (rather bizarrely) a 'lowercase stigma'.

Final sigma: ς
Stigma: Ϛ
Lowercase stigma: ϛ
