curved structure over an opening
A strong curved part of a building, bridge, or gate that goes over an open space and holds weight.
Padrão de uso:
an arch over [an opening]

Learners sometimes confuse 'arch' with 'archway'. 'Arch' is the curved structure itself, while 'archway' often refers to the opening that you walk or drive through.
Sinónimos
archway (Almost the same meaning, but often emphasizes the passage or opening created by the arch.)
|
vault (Larger and usually refers to an arched ceiling or roof rather than a single opening.)
Antónimos
flat lintel (A straight horizontal beam over an opening instead of a curved supporting structure.)

curved part of body or object
The curved part of something, especially the bottom part of your foot that does not touch the ground when you stand.

instep (Refers specifically to the upper part of the foot; often overlaps in everyday use when talking about foot shape or pain.)
|
curve (More general word for a bent line or surface, not limited to the body.)

chief or most extreme
Used before a noun to mean the main or biggest example of something, especially a person who is your main enemy or rival.
Padrão de uso:
arch [enemy/rival/villain]

Sinónimos
chief (Very close in meaning; more common in modern English and used with a wider range of nouns.)
|
principal (Formal; often used for official roles or reasons rather than enemies or rivals.)
Antónimos
