What's that? A vertical palindrome?

No, it's Dutch for acrostic. It's interesting how the sound went from Greek [kʰ] to French [ʃ] to English [k̚] influenced by spelling. English acrostic > Greek akros 'head' + stikhos 'line (of verse); row' (cf. stichometry 'counting lines of poetry').


Ceci n'est pas un seing.
