Synonym discussion

Sense: noun/1

For the garden sense, arbor is closest to pergola, trellis, gazebo, and bower, but each gives a different picture. An arbor is usually a smaller plant-covered frame over a path, gate, or bench. A pergola is often larger and more architectural, with posts supporting an open roof over a sitting area or walkway. A trellis is mainly a support for climbing plants and may stand against a wall instead of making a sheltered space. A gazebo is a freestanding garden building with a full roof, not just a vine frame. Bower is the most literary choice and suggests a leafy retreat. You might walk under an arbor, train beans up a trellis, or drink tea in a gazebo.

Etymology

Anglo-FrenchMiddle EnglishEnglish

The garden sense of arbor came into English through Anglo-French from a word linked to herbs and planted growth. That history fits a shaded frame covered with vines. The machine sense is a later extension, using arbor for the central support that other parts are fixed to or turn around.
