*deu- 2

"blissful, imparting bliss," 1630s, from French béatifique or directly from Late Latin beatificus, from Latin beatus "blessed, happy," past participle of beare "make happy, bless" (see Beatrice) + -ficus "making doing," from combining form of facere "to do, to make" (from PIE root *dhe- "to set, put"). Related: Beatifical (c. 1600); beatifically.

1530s, "to make very happy," from French béatifer, from Late Latin beatificare "make happy, make blessed," from Latin beatus "supremely happy, blessed" (past participle of beare "make happy, bless;" see Beatrice) + -ficare, combining form of facere "to make" (from PIE root *dhe- "to set, put"). The Catholic Church sense of "to pronounce as being in heavenly bliss" (1620s) is the first step toward canonization. Related: Beatified; beatifying.
