Related to Latvian laime, Old Prussian laeims (laims, “rich”), with further origin disputed: * Per Fraenkel, from the same root as léisti (“to allow”). The verbal form is attested with a now-rare meaning of "to create", which Fraenkel uses to bolster his argument. * Per Smoczynski, from a secondary o-grade of lémti (“to determine”). It is worth noting that the root underlying this word also serves as the namesake of Laima, the Baltic goddess of fate and pregnancy.
