usage

The 柞 reading is a bound proper-noun reading, used essentially only in 柞水, a county in southern Shaanxi. For the oak tree, use the 柞 reading.

radical

木 mù

tree; wood

Left is the tree radical 木, marking the character as a kind of tree — here the oak, valued for its hard timber and for feeding silkworms.

phonetic

乍 zhà

suddenly (phonetic)

Right is 乍, purely for sound; it gives the zhà reading directly and the zuò reading by a shift. The same phonetic drives 作 and 炸.
