adjective

[From Latin undecim (eleven), from unus (one) + decem (ten), + -ennary, from annus (year).]

"It appears from an undecennary account laid before Parliament."
E. Stiles; 1847.

Eleven, onze, once, elva, undici... some people see double but this week we're seeing eleven (from Old English endleofan, literally "one left" after counting 10).

Today, March 14, marks the eleventh anniversary of the founding of Wordsmith.org. On this undecennial we thank you, our readers, for being part of us.

To mark the occasion, this week we'll feature words connected in some way with eleven. By a happy coincidence, the number of letters in today's word is eleven.
