I often use the word people to mean multiple persons. However, I’ve noticed that sometimes people will laugh/smirk when I use it. For example, one time I was talking about how my sister and her family/household travel often, saying, “Those people travel a lot,” and the person repeated those people and gave a slight laugh. I’m wondering if I may be giving some sort of unintentional implied message when I use that word.
Does the word people mean anything other than multiple persons, such as a group of persons united by a common identity (family, experience, nationality, ethnicity, etc.)?
It’s not “people vs persons” but “those people vs they”.
Conversationally, “those/these” distances you from the group you are talking about, which is humorously weird when it’s your family you’re talking about.
It’s not the meaning of the words, but habitual (and often fleeting) attribution around them that tripped you up.
PS: “People” are uncountable, “persons” are countable. That’s basically the whole difference between the two plurals. Although it’s rapidly disappearing, as “ten people” won’t raise a single eyebrow in a conversation.
