To the extent that these pairs do differ, the compound preposition "on(to) conveys the completion of a action, while the simple preposition "on" points to the position of the subject as a result of that action. This distinction helps us
understand haw directional and locational prepositions are related. They stand in the relationship of cause and effect.
Anagahan fell on(to) the floor.
Vil is on the floor.
The plane landed on the runway. (not on(to) the runway)
Sam hang the decoration on the Christmas tree. (not on(to) the tree.)
mmmmmmm, hmhm...ok, i get the difference among the examples stated above....Thank You!
just some additional questions, to make myself sure I really got this
this is the example actually which invoked the question I posted
eg. A whole range of new electronic household appliances comes onto the market
it was stated that onto needs to be used, does not give on as an "or-option", so is it because " household appliances coming onto the market" is seen as some sort of completion of the action (even though the household appliances keep coming, the ones that had already come, are seen as something complete)?
it does get a bit confusing
and from what I got, if im not sure whether to use on or onto, the use of on would be correct?!
