Slate Slate Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates
Theophoric name (Joshua), "Yeho-tzedek", "Zekharya" (Zechariah). "Yahū" or "Yah" is the abbreviation of YHWH when used as a suffix in Hebrew names; as a prefix it appears as "Yhō-", or "Yo". It was formerly thought to be abbreviated from the Masoretic pronunciation "Yehovah". There is an opinion that, as Yahweh is likely an imperfective verb form, "Yahu" is its corresponding preterite or jussive short form: compare "yiŝthawe" (imperfective), "yiŝtáhû" (preterit or jussive short form) = "do obeisance".
