A portion of「clothing」from which one must「extract」oneself. Taking off a shirt or blouse with SLEEVES from which the wearer must「extract」each arm…yet, this same reasoning could be applied to any clothing, not just to SLEEVES, and to any part of one's body, not only an arm with a hand at one end…well, let's restate that: not only a long arm with a hand at one end.
　「Cloth used for extraction, cloth for rod's plugged orifice, cloth with a cause」perhaps relates to the English expression,「wearing one's heart on one's sleeve」(more likely, the original phrase was「wearing one's heart in a sleeve」) with the limited understanding that 心 exclusively meant 'heart' as smarmy jargon brought back to Britain by the expelled drug lords who peddled opium: HIDING AN ITEM by wearing one's 心 appendage spewing venom within a SLEEVE would convey to everyone just how bad the condition actually was/is, and therefore was some sort of plea for sympathy, an expression of how painfully sensitive the genitals were…how the sufferer felt would then have been obvious to other people. Netting with sleeves were used to hold medical herbs in place when treating an infection in a poultice applied to one's 心, a spewing appendage. See all the related glyphs combining meanings of SLEEVE with a stinky, pulled-to-one-side, rancid sticky fluids with a burning short arm within.
　HIDING ITEMS in one's sleeve also applies in Japanese: a kimono style of clothing has long, large, square sleeves into which small items might be hidden or carried, such as keys, a wallet, smokes and a lighter, etc., and from which these items must later be「extracted.」Pockets are not normally found on traditional Japanese formal clothing. A SLEEVE of clothing being worn is a sort of「clothing, plugged orifice」requiring「vertical motion」in order to「extract」each arm.
