in Luke 2:29-32, beginning “Nunc dimittis servum tuum” (“Now lettest
thou thy servant depart”). [Late Latin : Latin nunc, now + Latin

Well, nephy, you are not gone yet?

Yes, I am,  nunc.

Tis, utter nonsense, nephy, nonsense. 

Gaberbocchus by Hassard H. Dodgson (Charles Lutwidge
         Dodgson's uncle) 

Hora aderat briligi. Nunc et Slythia Tova
Plurima gyrabant gymbolitare vabo;
Et Borogovorum mimzebant undique formae,
Momiferique omnes exgrabuere Rathi.
