What does speeded mean?
Speeded is the past tense and past participle of speed, meaning to move or make something move more quickly. It can describe a person or vehicle increasing its pace, as in “the car speeded along the highway,” or the acceleration of an activity, as in “the company speeded up production.” The related form sped is more common in everyday English, while speeded is especially used when a process has deliberately been accelerated, often in the construction “speeded-up.” Its wording gives the impression of purposeful quickening: a vehicle simply speeds, whereas a procedure is often speeded up to meet a deadline or improve efficiency. Speeded should not be confused with sped, which has the same grammatical function and meaning but is more frequent in general usage.
