About this pattern

Explanation

あるいは is a formal, written way to present alternatives or possibilities. It often replaces または in more literary or logical contexts, signaling a choice between two or more options. It can also introduce a tentative possibility rather than a definite fact, giving a sense of speculation or formal consideration. Use it in essays, reports, or presentations when you want to present multiple paths or hypotheses without asserting one as the definite outcome.
