What does oscillating mean?
Oscillating means moving repeatedly back and forth between two or more positions, values, or states. The word is especially associated with physical movement, such as a swinging pendulum or an oscillating electrical signal, but it also describes numerical and social variation: a price may be oscillating, or a person’s opinion may oscillate between approval and disapproval. Its connotation is generally neutral, although in technical contexts it can suggest a regular or measurable cycle. In everyday use, oscillating is often more vivid than merely changing because it emphasizes repeated movement in opposite directions. The related forms oscillation, oscillate, and oscillator are common in science, engineering, economics, and writing about patterns, systems, and uncertainty.
Moving repeatedly and regularly back and forth between two positions, directions, or values; fluctuating.

Can describe a physical system, a measurable value, or an abstract pattern such as changing prices or opinions.
To move repeatedly and regularly back and forth between two positions, directions, or states.

The present participle is commonly used as an adjective before a noun, as in “an oscillating value,” and as a gerund in constructions such as “the market is oscillating.”
From pendulums and electrical currents to fluctuating markets, oscillating captures the recurring motion of a system moving between opposing states.

Where does oscillating come from?
The word comes from Latin oscillare, meaning “to swing,” and ultimately from the noun oscillum, a swinging or oscillating object. English borrowed related forms in the 17th century, developing oscillate and oscillation before the present participle oscillating became established. The family also includes scientific and technical forms such as oscillator and oscillatory, which retain the same sense of regular back-and-forth movement.
