A small bead or something resembling a small bead; a young or minor beadle.
From bead plus the diminutive suffix -let (as in 'leaflet,' 'booklet,' 'piglet'). The suffix -let in English creates small or minor versions of things. Applied to 'bead,' it means a tiny bead; applied metaphorically, it could mean a minor beadle.
Beadlet has a delightful double life—it can literally mean a tiny bead (useful in jewelry-making contexts) or humorously refer to a petty, small-time beadle, showing how English diminutives can work literal and figurative magic.
