And a “perambulator” is a kid stroller. It was an enlightening moment when I first came across that word in Neil Stephenson’s “Seveneves”, delved into its etymology and then realised why my British friend called the stroller a “pram”. This is just a contracted form of perambulator.

It did not occur to me that there’s actually also a verb for it, so thank you for pointing that out! I love it, and I will use it henceforth!
