Etymology: "Omittable" is a plain formation: the verb "omit," borrowed from Latin "omittere," meaning "to let go, leave out," combined with the English suffix "-able," which turns a verb into an adjective meaning "capable of being" the action. Something omittable is therefore something that can be left out without loss. The suffix does most of the work here. "-able" attaches freely to English verbs, so "omit" plus "-able" yields a word that describes whether an item, step or sentence can be dropped while the whole still functions. In practice it is most often used of things like optional steps in a procedure or passages a reader may skip.
