FAQ
Frequently Asked Questions
No, it is a highly specialized architectural term rarely encountered outside classical design, restoration, or art history contexts.
Cyma reversa is concave then convex (like an S on its side). Cyma recta is convex then concave (like a soft wave). The order of the curves is reversed.
This is extremely uncommon and would likely not be understood by a general audience. Its usage is almost exclusively literal and technical.
In both British and American English, 'cyma' is pronounced /ˈsaɪmə/, rhyming with 'lima' as in Lima bean.
