Thank you guys, reading your posts is more fun than anything else!
This is about all Beatrix Potter's work. I left it a cache version so that "round" and "around" are highlighted to be found easily.
In her work, there are only two instances of "around."
(1)After a time he began to wander
about, going lippity--lippity--not
very fast, and looking all around.
(2)he seemed to be
sniffing around.
The rest are all "round."
Do you think Beatrix Potter could have chosen "round" in place of "around" in (1) and (2)?☝
In my experience, yes you
could use `round in those two examples. But, there is a reason that she didn't, and it is as follows: (In my humble opinion!)
When you use "`round" as an abbreviation of "around" it carries with it the idea of going around something a little more tightly. It's a little closer to the idea of something being circular or repetitive. The whole idea of "around" can also mean going in circles, but, it's also commonly used with other expressions. e.g.
Have a look around the store.
I went downtown and walked around.
This usage has a slightly different idea behind it, as in, you are wandering or investigating the entirety of something but the purpose is not 100% clear. The direction is not necessarily a circle either, you could cross your own path many times. This is why in the examples you cited, the idea of searching or lacking a direct purpose is present. So in some examples, `round and 'around' are both okay, and in some examples 'around' communicates the idea of searching or going somewhere with a somewhat vague purpose.
Examples where you wouldn't pronounce the 'a' could include:
Merry-go-round
"The rabbit hopped `round the tree and surprised his friend"
"She wasn't clear, she spoke in a very roundabout way."
Examples where both are okay:
"I'm going `round/around the block."
"Shes down `round/around the river somewhere, go find her"
Examples where 'around' is better would include the ones I mentioned re: searching/looking, and the examples that you originally posted.
