a journey to a place, where you stay for a short time, and then come back again
go on/make/take a trip
I completely understand the meaning of it.
An ELL post uses “trip” this way
I’m going to have a trip to Sweden.
Ngram Viewer also shows that use.
Do “have a trip” and “go on a trip” mean the same thing? Are “have a trip” and “go on a trip” interchangeable in any cases?
Last month, I went on a lovely trip to New York City.
Last month, I had a lovely trip to New York City.
“I have a trip”, in that form, is unusual. If you look at the actual texts that your Ngram results are taken from, most of them use “have a trip” as part of longer expessions, like
“have a trip coming up”
“have a trip planned”
“had a trip cooked up”
“had a trip scheduled.”
“had a trip to take”
There are some examples of “I had a trip” with the meaning of
“I went on a trip”. or “I took a trip.”, but they are so rare that I would call it unidiomatic.
