I am just wondering, why larĝa means "wide" and not "large". So I looked to the Etymology Dictionary and here's the answer:
large (adj.): c. 1200, of areas, "great in expanse," of persons, "bountiful, inclined to give or spend freely," from Old French large "broad, wide; generous, bounteous" (12c.), from Latin largus "abundant, copious, plentiful; bountiful, liberal in giving, generous" (source also of Spanish largo "long," Italian largo "wide"), a word of unknown origin.
