What does slowed mean?
“Slowed” is the past tense and past participle of “slow,” and it can also function as an adjective for something operating or moving at a reduced rate. As a verb, it is transitive when something causes a reduction in speed or pace, as in “The storm slowed traffic,” and intransitive when movement or progress becomes less rapid, as in “The car slowed before the junction.” The form is especially common in formal, technical, and media contexts, including “slowed economic growth,” “slowed audio,” and “the pace slowed.” In everyday conversation, “slowed down” is often more familiar and conversational: “He slowed down to avoid the cyclist.” The adjective sense extends beyond physical motion, so music, speech, development, and even a signal may all be described as “slowed.” Although the word is entirely standard, its clipped participial quality can sound more formal or technical than “reduced” or “decelerated.” Its usefulness lies in this flexibility: it can report either a completed action or a resulting state without requiring a separate clause.

Where does slowed come from?
“Slowed” was formed by adding the regular English past-tense and past-participle ending -ed to “slow.” “Slow” comes from Old English slāh, an adjective meaning “not quick” or “dull,” and belongs to a Germanic word family associated with slowness, idleness, and sleep. English relatives include “sloth,” “slothful,” and “sluggish,” while related forms appear in Dutch and German.

How slowed is actually used
The adjective use is especially common in media, technical writing, and descriptions of audio, speech, or signals. In general conversation, “slowed down” often sounds more natural than the bare transitive form “slowed.” As an intransitive past-tense verb, it is fully standard.
