What is difference between trolley and strolley?

Answer 1

Well, darling, a trolley is typically a wheeled cart used for transporting goods or passengers, while a strolley is just a made-up word that people sometimes use to refer to a suitcase with wheels. So, in short, the main difference is that one is a real thing and the other is just a cutesy way of saying "rolling suitcase." Hope that clears things up for you, honey!

Answer 2

There is no such word as "strolley", at least not as a common noun -- although there is a brand of suitcase cum pushchair marketed under the name "Strolley".

The trade name is probably a blend of American English "stroller" (= British English "pushchair") and British English "trolley" (= American English "hand truck / cart").
