Trip,travel,journey, voyage

A trip is anytime you leave home, go somewhere, and return. You can take a trip to the store or to the South Pole. A trip requires a destination and at least a brief stay; you can't take a trip to the end of your street (unless you live on the Appian Way or something). You can go on a trip, which implies a longer time away from home; you can't go on a trip to the store. There are figurative uses,

enoon It takes on the figurative meanings that "travel" would otherwise carry, for example, the journey of life.

Thanks Enoon, very helpful,awesome.

I don't think I understand your question. Could you ask it in another way, please?

sure.
Well, can you please tell me how to use "otherwise" especially with "would" ? when can we use "otherwise"?in grammar.

"Otherwise" is just an ordinary adverb, grammatically speaking. It means "under different circumstances" here. To analyze my phrase, "that 'travel' would otherwise carry", you can put "otherwise" after the verb: "that 'travel' would carry otherwise".

Thanks,so 'otherwise in your phrase means:journey is the same as travel except for figurative meaning.
Am I right?

Oh, I see what you mean. No, I mean that if the word "journey" did not exist, many more figurative meanings would have had to attach to "travel".

While we are on the subject of "journey" vs. "travel", I think I overstated the similarity between the two words. A journey is not "a travel". "A travel" is impossible in English in the sense of "trip", but "a journey" is normal.

Thanks.Now I got what you mean.
