Slept and sleeped
Hello there!
I know that the verb “to sleep” can have to forms in the past – “sleeped” and “slept”. Could native speakers explain me the difference between them. As I realize “slept” is grammatical and literary correct, spread in all English speaking parts of the world. What about “sleeped”? Is this form valid? Do the people use it in all English speaking countries? Will I look ridiculous if I say “I sleeped” among the people for who English is a mother language?

Answer

Maybe not ridiculous, but "sleeped" is a red flag that indicates you might not know English very well. Use "slept" and never look back. :)

Answer

I don't think you'll look ridiculous but "slept" is the much more common form.

Very people say "sleeped".

Conversely, the past tense of "to learn" can be written "learned" or "learnt" but it's far more common to see the -ed form.

Answer

Actually "sleeped" is not an actual word. "Sleep" is an irregular verb and doesn't follow regular verb patterns so just adding "-ed" at the end of the word is incorrect. Some other irregular verbs that follow this pattern are "Creep", "Keep" and "Weep". They're conjugated like this:

Sleep:
I sleep (Present)
I slept (Past)
I will sleep (Future)

Creep:
I creep (Present)
I crept (Past)
I will creep (Future)

Keep:
I keep (Present)
I kept (Past)
I will keep (Future)

Answer

That hardly means it's widely acceptable. Stick with standard English.

To Peachey - "Sleeped" I heard from a native speaker from NY city.
