Not really, can you explain it to me?

Yeah, I was surprised it could even reach that high!

Root Explanation
The word 'onto' originates from the combination of 'on' (from Old English 'on', meaning in or upon) and 'to' (from Old English 'to', meaning toward or in the direction of). The word 'onto' describes a movement or position directed towards a surface or object.
Memory Tip
Think of 'on' meaning to be in contact with something and 'to' meaning moving towards it — this helps you remember that 'onto' indicates a direction towards a surface.
