IPA: //ˈsɜːrbeɪst//
KK: /sɜrˈbeɪst/
Relating to a type of arch that has a rise that is less than half of its total width.
The architect designed a surbased arch for the new bridge.
This word originates from the combination of 'sur-' (from Old French, meaning over or above) and 'based' (from the verb 'base', meaning to establish or found). The word 'surbased' refers to something that is established or founded above a certain level or standard.
Think of 'sur-' meaning 'over' and 'based' meaning 'established' — so 'surbased' means something that is established above a certain level.
