Etymology: "Slatiest" is simply the superlative of "slaty," which describes something resembling or containing slate, the fine-grained rock that splits into thin flat sheets. Slaty is formed from "slate" plus the suffix "-y," which turns a noun into an adjective meaning "having the qualities of" or "like" the noun. Slate itself came into English from Old French, where a word for a split stone or roofing slab was in use, and it has long been used for roof tiles, writing surfaces and the grey-blue colour of the rock. The superlative "-iest" follows the regular pattern for adjectives ending in "-y," where the "y" changes to "i" before the ending is added, giving forms such as "slatier" and "slatiest." Here "slatiest" names the greatest degree of slatiness among several things being compared.
