La rosca de un arco

[lpwe]

Having trouble. I'm translating and I do not know what the "rosca de un arco" is. I know arch, but what is "rosca"? The answer or any ideas would be greatly appreciated. Thanks!

is rosca "thread"??

[lpwe]

It is thread in different contexts, but here I need "rosca" as it applies to an arch. I don't think "thread" is applicable here, at least as far as I've been able to find out. Thanks though!

you're welcome. But I'm not really sure if it actually means thread :P

[lpwe]

Well, it does mean thread. For example, the thread of a screw (aka, the line that spirals around a screw). It does not, however, mean the kind of thread you use to sew, that's "hilo".

oh ok

I think could be ring shaped of kings, (La rosca de Reyes), or if you have other kind of mean for the whole sentence please, let us know, because I don't know if my attempt could help you.

If you could post the whole sentence, the context would help.

Edit: After some research, it appears that the "rosca" of an arch is a series of concentric steps or molding, receding toward the arch. It can also be used for a window or door. Apparently, "order" is the correct architectural term for this in English.

so its not "thread"

[Tomisimo]

Rosca can mean thread, as in the thread of a bolt, but in this context it doesn't.
