Not moving; motionless
Not moving; staying in one place.
Padrão de uso:
[something] is/remains stationary
Erro comum:
Learners often confuse 'stationary' (not moving) with 'stationery' (paper, pens, etc.) because they sound the same. Another mistake is using 'stationary' as a noun (*I bought a stationary*), which is wrong; it is an adjective and must describe a noun (*a stationary car*). Learners also sometimes overuse 'stationary' where simple 'still' sounds more natural in everyday speech (e.g. *I am still* instead of *I am stationary*).
Sinônimos
motionless (Often suggests a complete lack of movement, while 'stationary' can also mean fixed in place even if small movements happen inside.)
|
still (More common in everyday speech, especially about people, animals, or water; can also mean 'quiet' or 'calm'.)
Antônimos
moving (Directly describes being in motion, the opposite of not moving.)
|
mobile (Able to move or be moved, the opposite of being fixed in one place.)

2
Not changing over time (technical)
In science or math, not changing over time in its main numbers or pattern.
Padrão de uso:
[something] is stationary
Erro comum:
Learners may think this technical sense always means 'not moving in space', but here it means 'not changing over time' in numbers or patterns. It is mainly used in statistics, physics, and similar fields, not in everyday talk about people or objects.
Sinônimos
stable (Suggests not changing or varying; broader and less technical than 'stationary' in this sense.)
|
steady (Means regular and unchanging, but is more general and less precise than the technical term 'stationary'.)
Antônimos
variable (Describes something that changes over time, the direct opposite of stationary in this technical sense.)
|
dynamic (Emphasizes active change or development over time, contrasting with unchanging properties.)
