The official blazon of the University of Nottingham describes
... inscribed with the words 'Quarente Ostium', ...
for which I can not find a proper translation. I'm pretty sure ostium here refers to some type of door or opening of some sort. I'm not too sure how to translate quarente. I believe it could originate from quærēns (from this wiki page) meaning something to seek, gain or ask.
Is it reasonable to translate this as seek every opening or is there a more accurate translation?
