Sŏl'i-dăr'i-ty, n.
[Fr. solidarité, from solide.] An entire union, or consolidation, of interests and responsibilities; fellowship.
Solidarity—a word which we owe to the French Communists, and which signifies a community in gain and loss, in honor and dishonor, a being (so to speak) all in the same bottom—is so convenient, that it will be in vain to struggle against its reception. Trench.
