I don't think I would word it like that. I'm not saying it's wrong because I honestly don't know if it would be grammatically correct to word it like that, but I don't think I've ever heard "still probably". I would either say "He is probably still asleep" or "He is probably asleep still". The first one "He is probably still asleep" is the best option.
Sounds good! While as a native speaker, 'still' isn't one of the words that give me problems, there are some I find more troublesome, the placement of 'only' in a sentence is one. Ex: I don't want you to think only this, or this only, as one of the words that only has this problem.
I wish duolingo would discuss sentence structure furthur with adverbs. The structure of this sentence confused me at first, because the adverbs came after.
I'll post to you what I found online @ lingolia for if an adverb is in the middle of a sentence.
- The adverb generally comes after the dative object and before the accusative.
- To add emphasis onto the adverb, you can place it after the accusative.
- You cannot place adverbs directly before pronouns. If both objects are pronouns, place the adverb after them.
- If there is no object, the adverb goes after the verb.
We would not say "he may still sleeps" but "Maybe he is still sleeping"
It is to do with it being an on going action. He is in the middle of sleeping and it is still going on.
If you ask " what does he do between 23h and 8h?" Then you could answer "He sleeps" because it is not on going. In that case we wouldn't say "He's sleeping"
