Onto ( or ) On To :



“Onto” and “on to” are often interchangeable, but not always.


Consider the effect created by wrongly using “onto” in the following sentence when “on to” is meant:


“We’re having hors d’oeuvres in the garden, and for dinner moving onto the house.”


If the “on” is part of an expression like “moving on” it can’t be shoved together with a “to” that just happens to follow it.
