Hi. I am learning Greek, not Latin. Here is a question non-the-less.
The school where my daughter attends has NULLA DIES SINE LINEA on the crest. (I assume this is Latin ???) Can someone tell me what this means? Thanks in advance.
NULLA DIES SINE LINEA
It looks like “Not a day without flax/thread/string (?)” but “NULLA” does not match “DIES” in gender so if it is meant to match “LINEA” I guess that it would mean “A day without no thread”. I seriously hope I have made some idiomatical error or that “DIES” can be found as a feminine…
Dies can be masculine or feminine depending on whether it’s a normal day or a special day (and I can never remember which is which). Linea is a line (in the ablative).
So it’s “never a day without a line” (i.e. writing/drawing something), a good motto for a school, but I’d expect more than one line for the amount I pay.
Pliny explains the origin
Apelli fuit alioqui perpetua consuetudo numquam tam occupatum diem agendi, ut non lineam ducendo exerceret artem, quod ab eo in proverbium venit
In general, Apeles always had the habit that he was never so busy with things to be done that day that he would not execise his art by tracing a line, and this came as a proverb from then.
I really must get out more.
I still think my translation made more sense 
just kidding…
