"A 2-year-old girl can propel a pencil or pen and turn the pages of a book one by one."
Does "propel" mean "try to imitate the movements of writing and drawing"?
Sounds like that, doesn't it? That's a very interesting use of propel.
propel, vb. cause to move, forward or onward, with force, especially mechanically;e.g., propel a boat by rowing.
All the best.
