Can you end a sentence with the word however?

You can't end a sentence with "however" in standard English. "However" is a conjunctive adverb, meaning it connects two clauses, and it typically appears at the beginning of the second clause.

For example:

* "I was planning to go to the beach, however, it started raining."

If you want to use "however" at the end of a sentence, you would need to restructure it. For example:

* "It started raining, which was unfortunate, however."

In this case, "however" modifies the phrase "which was unfortunate" and clarifies the speaker's feeling about the rain.
