Different, a.
Etymology: [L. differens, -entis, p. pr. of differre: cf. F. différent.]
1. Distinct; separate; not the same; other. "Five different churches." Addison.
2. Of various or contrary nature, form, or quality; partially or totally unlike; dissimilar; as, different kinds of food or drink; different states of health; different shapes; different degrees of excellence. Men are as different from each other, as the regions in which they are born are different. Dryden.
Note: Different is properly followed by from. Different to, for different from, is a common English colloquialism. Different than is quite inadmissible.
