Different \Dif"fer*ent\, a. [L. differens, -entis, p. pr. of
differre: cf. F. diff['e]rent.]
1. Distinct; separate; not the same; other. "Five different
churches." --Addison.
[1913 Webster]
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;

[1913 Webster]
Men are as different from each other, as the regions
in which they are born are different. --Dryden.

for different from, is a common English colloquialism.
Different than is quite inadmissible.
