The state, quality, or condition of being British; the collective identity or character of British people.
From British + -hood (a suffix denoting condition or state, as in childhood, manhood). Rare term formed through productive English word-building.
This word is so uncommon that it barely exists in modern usage—it's a reminder that just because English can build a word (British + hood = britishhood), doesn't mean speakers will actually use it.
