I usually see these two words used together as in "hustle and bustle". I consider them as synonyms but I would like to know that do they have any differences.
Then I looked up "bustle" in Merriam-Webster dictionary and found the definition as follow:
1: to move briskly and often ostentatiously
//bustled around the kitchen
I'm a little surprised to see the word "ostentatiously" here. I've never known "bustle" has this connotation. Does the definition with "ostentatiously" make sense? What is the difference between bustle and hustle?
Updated: there is a line in Central Park (TV series), which is as follows:
... a place that all the bustle seems to pass.
Is it correct if I say "a place that all the hustle seems to pass"?
