What’s the past tense of “speed”?

The consensus seems that both speeded and sped are both correct past tense and past participle forms of the verb speed.

That said, sped is speedily (adverb) becoming the more prevalent past tense and past participle, with speeded mainly being used as a phrasal verb, (followed by –up). Feel free to speed through this one—and enjoy the reoccurring dad jokes.

The gist on the verb ‘speed’

The topic is the word speed, which can be both a noun or a verb. As a noun, it refers to “the rate at which an object covers distance.” As a verb, it refers to “moving along quickly”; as in “we sped up when we heard the dog’s barks getting closer”.

So, for example, in describing myself, I could tell someone that ‘I’m not the kind of person who speeds out of bed in the morning’. This is true, and also shows speed in the third-person present singular form. Take a look at the other verb forms of speed:

simpleI speedI sped/speededI will speed
continuousI am speedingI was speedingI will be speeding
perfectI have sped/speededI had sped/speededI will have sped/speeded
perfect continuousI have been speedingI had been speedingI will have been speeding

When to use “speed” vs. “sped”

The simple past tense of speed (rhymes with beed) is sped (rhymes with shed). But what’s the difference between the simple past tense sped, and the past participle sped (or speeded)?  See a comparison of both past forms of the verb sped in context:

The paperboy sped/speeded through the neighbourhood on his bike

They had speeded/sped along the road towards the village.

What’s the difference between the two sentences? Both are in the past tense, and so describe actions or states that have been completed entirely in the past.

The difference is the use of auxiliaries in the past perfect (such as had) to form other aspects of tense, along with the past participle verb form (e.g., sped or speeded).
