Erayga "nalalka guriga" caadi ahaan waxa loola jeedaa nalalka masraxa ama goobta bandhigga kale ee loo daaray si ay u iftiimiyaan aagga dhagaystayaasha ka hor ama ka dib bandhigga, inta lagu jiro kala-guurka, ama inta lagu jiro nasashada ficilka ee masraxa. Nalalkani waxay u oggolaanayaan dadka inay si badbaado leh u wareegaan oo ay helaan kuraastooda, waxayna sidoo kale bixiyaan calaamad muujinaysa in bandhiggu uu ku dhow yahay inuu bilaabo ama dhammaaday.
