Nānā nui o ka hao hao
ʻO ke ala kaʻaahi, i ʻike mau ʻia ʻo ke kila ala kaʻaahi, he kila kūikawā i nā huahana metala i hoʻohana nui ʻia no nā ala kaʻaahi. Lawe ke kaʻaahi i ke kaumaha a me ka ukana ikaika o ke kaʻaahi. ʻAʻahu kona ʻili, a pā ke poʻo. Aia ke kaʻaahi i ke koʻikoʻi piko nui. ʻO ka paʻi paʻakikī a me ka lawelawe lōʻihi e lawe mai i nā pōʻino i nā alahao.
