Difference between Travel, Trip or Journey?

1. What's the difference between Travel, Trip of Journey? (From VOA)

 

[TRAVEL]

“Travel” is a verb that means “to go to a place and especially one that is far away.”
Far can mean long distances within the same country or to other countries.

For instance:
I have a friend who travels abroad a lot for work.
“Travel” can also be a noun that relates to the act or activity of traveling in general.

For instance:

The future of U.S. travel is not likely to include high-speed rail.

A common mistake with “travel” is confusing it with “trip,” like this:
I bought this souvenir on my travel to California.
We rarely use “travel” with “my,” “your,” “a” or other determiners.

[TRIP]

The word “trip” is a noun that means “the act of going to another place and returning.”

For example:
I bought this souvenir on my trip to California.

We also often use the verbs “go on” or “take” with “trip,” like this:
I took a long trip to California last year.

And, we say things like “day trip,” “business trip,” and “road trip” to describe different kinds of trips.
We do not use the word as a verb for travel.

[JOURNEY]

The word “journey” is a noun that means “the act of going from one place to another.”
But, we use it in two specific ways:
One is to talk about a trip that takes a long time,
especially if there are either difficulties or discoveries in transit.
For instance:
I hope to take a journey across America by car one day.
The other is to talk about a trip that does not involve physical distance,
but instead is a process of learning or self-discovery,
as in this:
A 10-day vipassana is a kind of spiritual journey.
We rarely use “journey” as a verb except in some styles of writing.

2. SUMMARY

The key difference between trip and travel is that trip is a noun
that indicates a relatively short journey whereas travel is a verb referring to the movement of people
between distant geographical locations.

In brief, it is not possible to use the words trip and travel interchangeably
as they belong to different grammatical categories.
