Derivation of the botanical name:
Crataegus, Greek kratus, kratys "strong, mighty," kartos "strength" and akakia,akis "tip, thorn, a sharp point" or aigos "a goat," Latin crataegum for the kernel of the fruit of the box-tree (Plinius).
aronia, Greek, for medlar-tree.
azarolus, from Arabic Za'rur, the name of the fruit.
Hawthorn from haw, originally an Old English term for hedge (from the Anglo-Saxon term haguthorn, "a fence with thorns"), also applies to the fruit.
The Hebrew name: עוזרר, ozrar is mentioned several times in the Mishnah (Tithes, Demai, Kilayim, Okatzim), by the names ozrar or ozrad. Since in Arabic the name za’arur, za'rur (tiny, i.e. tiny apple) has been preserved, it is called ozrar in Modern Hebrew.
