Noah Webster
Although
ALTHO'UGH, altho', obsolete verb, or used only in the Imperative.
Grant all this; be it so; allow all; suppose that; admit all that; as, 'although the fig tree shall not blossom.' Habakkuk 3:17. That is, grant, admit or suppose what follows - 'the fig tree shall not blossom.' It is a transitive verb, and admits after it the definitive that - although that the fig tree shall not blossom; but this use of the verb, has been long obsolete. The word may be defined by notwithstanding, non obstante; as not opposing may be equivalent to admitting or supposing.
