c. 1300, poumgarnet (a metathesized form), from Old French pome grenate (Modern French grenade) and directly from Medieval Latin pomum granatum, literally "apple with many seeds," from pome "apple; fruit" (see Pomona) + grenate "having grains," from Latin granata, fem. of granatus, from granum "grain" (from PIE root *gre-no- "grain"). The classical Latin name was malum granatum "seeded apple." Italian form is granata, Spanish is granada. The -gra- spelling restored in English early 15c.
