describing the curved route a moon, satellite, or other space-travelling body follows as it moves repeatedly around something larger like Earth, the Sun, or a planet
Aarav spent three years studying the orbital path of distant comets.
orbital + path (the typical noun pairing)

orbital + speed/velocity (technical noun pairing)

文法句型
orbital + noun (path, mechanics, debris, velocity)
用法筆記
Used almost only before a noun (attributive). Common noun partners include path, speed, velocity, mechanics, debris, decay, plane. Rare in everyday talk outside science, news about space, and engineering.

in medical or anatomy texts, describing the bony hollow that holds the eye and the muscles around it
Dr. Sayaka asked for a scan to check the patient's orbital bone.
orbital + bone (the most common medical pairing)
The boxer suffered an orbital fracture after the heavy punch.
orbital fracture = a break in the bone around the eye
Surgeons rebuilt the orbital floor using a thin piece of plastic.
After the car crash, Kofi was treated for swelling around the orbital rim.
- ocular
also medical, but refers to the eye itself rather than the bone around it
文法句型
orbital + body-part noun (bone, floor, rim, cavity)
用法筆記
Strictly medical or anatomy register; everyday speakers say around the eye or eye socket. The noun is the eye socket itself; 'orbital' is the adjective form for muscles, bones, fractures, or surgery in that area.

describing a road, motorway, or route that loops right round the outside of an urban area so drivers do not need to enter the busy middle

orbital + motorway (typical British pairing)

- ring
common in 'ring road'; same idea but used as a noun modifier rather than an adjective
文法句型
orbital + road/motorway/route
用法筆記
Mainly British English. Often pairs with motorway, road, route, or section. Distinct from sense 1 (space): you cannot swap them — 'orbital traffic' on a motorway is not the same as 'orbital path' in space.

in chemistry and physics, a small region of space inside an atom where up to two electrons are most likely to be found at any given moment

orbital as 'cloud shape' (key chemistry teaching frame)
Two electrons in the same orbital must spin in opposite directions.
rule: two electrons per orbital (Pauli pattern)
The chemistry teacher asked Asher to label every orbital on the diagram.

- electron shell
a broader group of orbitals at similar energy; not the same as one orbital, but often discussed together
文法句型
the/a + orbital
atomic/molecular + orbital
用法筆記
Strictly a chemistry and physics term — different from a planet's orbit, because an orbital is a 3-D region, not a single line. Common left-modifiers: atomic, molecular, outer, inner, p-orbital, d-orbital.

a body piercing made from two small holes placed close together, usually on the ear, that are joined by one ring of jewellery passing through both holes

Christopher said his orbital took almost three months to heal properly.
文法句型
get/have + an + orbital
用法筆記
Used in body-modification and jewellery shops. The key visual feature is one ring passing through TWO holes — that's what makes it 'orbital' rather than two separate piercings. Often paired with 'piercing': 'an orbital piercing'.

a large road that has been built in a loop right round the edge of an urban area, used by drivers who want to skip the busy middle

文法句型
the + orbital
the + city name + orbital
用法筆記
Mainly British, mostly used with 'the' (the London orbital, the Birmingham orbital). Different from adjective sense 3 — here 'orbital' stands alone as the road itself; the adjective sense needs a following noun like 'motorway' or 'road'.
