Unleashing dogs into the crows or onto or on? Are all of these grammatical? I think I see on most often, and then onto and sometimes into, but I think into is not grammatical. Am I correct?
It would be - "unleashing the dogs onto the crows"
I will start by explaining the difference between in and on."on" is used when something is positioned above something else or on the surface of something."in" is used when something is inside something or surrounded or enveloped by a thing.
e.g Lie down on the floor
The painting is on the wall.
I am in my room
The difference between on and onto is that onto suggest a movement towards something( in and into also has the same difference except that "onto" is used for movement on the surface and "into" in used when a thing is getting surrounded or moving into a thing)
We climbed onto the building's roof
I stuffed the sweets into my mouth
The above definition clearly suggests that onto is the right choice here.
