であれEven if, Even, No matter

Functioning as an extension of である, the formal copula that is a combination of the conjunctive form of the auxiliary verb だ, and the う-Verb ある, であれ or であろうと will be used in order to express strong will or conviction.

あれ is simply the imperative form of ある, while あろうと is the positive volitional form combined with the case-marking particle と. Both structures are usually translated as 'even if (A), (B)', or 'no matter if (A), (B)'. Despite this, the more literal meaning of each is closer to 'so it's (A), (B) still won't be affected'. This just emphasizes the fact that (A) is of no relation to the result, like saying 'so what if it is' in English.

Both であれ and であろうと will primarily attach to nouns in sentences that express some kind of question or assumption through words like どんな or たとえ.

As both であれ and であろうと use structures that indicate strong will, these grammar patterns will frequently be used in sentences where the speaker is expressing their opinions or resolutions.
