however; whatever ~
Expresses 'however' or 'whatever', indicating that the outcome does not change regardless of the circumstances.
This pattern is used to say that something is true or will happen regardless of the situation or condition mentioned. It often appears in formal or written contexts, such as news reports, essays, or speeches. When speaking, you might use it to sound emphatic or literary, but it is not common in casual conversation.
The nuance is that even if the condition varies, the result remains the same. It can be translated as 'no matter how...' or 'whatever...'. For example, 結果はどうであれ means 'whatever the result is' and implies that your actions or feelings won't change. It is similar to にかかわらず but carries a slightly more concessive tone, suggesting a deliberate disregard for the condition.
When using with verbs, you typically use the past tense form (e.g., したはどうであれ) to indicate that the situation has already been considered. With nouns and な-adjectives, you can often drop the である and just say ~であれ, but the full ~はどうであれ is also natural.
