Rab is a masculine name with Scottish origins, traditionally used as a diminutive form of Robert. In Scotland, particularly in rural and Highland areas, Rab has long stood as an affectionate, familiar form of the name. The name Robert itself comes from Germanic elements meaning "bright fame." Rab's brevity gives it a straightforward, unpretentious quality that has made it enduringly popular in Scottish communities. Outside Scotland, the name is less common but carries an appealing simplicity. In literature, Rab appears in various Scottish works, including Robert Burns' poems. The name's concise form fits well with contemporary preferences for short, strong-sounding male names.
