【日本語の異形】以前は「流れ、液体」に「動きを止め、足がバラバラになる」が3回（澁）あり、「完全に止まる、つまずく」という意味で、その前は「流れ、切って動きを止める（2倍の：澀）」で、痛みを伴う手続きが各足で1回ずつ、2回発生することを表しています。下の2つの「動きを止め、足がバラバラになる」構成要素は、「乾いた粘着性、あらゆる方向への放出」（内側の「流れ」構成要素なし）に置き換えられ、おそらく口または肛門のように「しわが寄った」ように見えます。恐怖による下痢の後、軟便や便滴を我慢するために肛門がすぼまることがあります（足離断手術の前または手術中に自然に排便した場合など）。また、収斂剤は「止めて、止めて、その流れを止めて！」というように、望ましくない排泄物を止めるのに効果的です。収斂剤は、唇を自然にすぼめ、口の中を「乾燥してベタベタ」させます。
黄褐色は、下痢で薄めた便の色、または、永久に汚れた腰布の色、あるいは、この象形文字で表現されているのと同じ渋みのある未熟な柿の色に由来しており、未熟な柿はタンニンを含み、下痢を止めるのに使用されます。
Tardy の関連する意味がなぜ当てはまるかは、ご想像のとおりです。つまり、便秘で1回、2回、または3回遅れたということです。Hesitant, reluctant も明らかです。重度の下痢のときに両足で何かに飛び込んだり、収斂剤とわかっているものを食べたりはしないでしょうし、片足ずつ足の骨を砕かれるのを嫌がるでしょうから。
洗練された味覚や洗練さの意味は、おそらく「上唇が固く、口と直腸が常にすぼめられ、肛門にこもり」、解放も寛ぐもない状態と関連していると思われます。また、濃厚な食べ物の洗練された味覚と軟便が関連していることも示唆されており、肛門をすぼめたままにしておくと、誤って排泄したり、不適切な鼓腸が軟便につながり後悔の原因となることを避けることができます。

[Japanese variant] formerly「flow, fluids」with「cease movement, foot-dis-integrating」three times (澁) meaning「absolutely stop, stumbling」and before that「flow, cut and halt movement (doubled: 澀)」representing the painful process occurring twice, once with each foot. Bottom two「cease movement, foot-dis-integrating」elements were replaced by「dry stickiness, emissions in all directions」(without the inside「stream」element) and resembling「puckered」as perhaps a mouth or an anus. One's anus may be puckered after a bout of terror-induced diarrhea in order to hold back the loose stools and drippings (such as when spontaneously defecating prior to or during the foot-dis-integrating procedure), and an ASTRINGENT is often effective for stanching the unwanted discharge, as in「stop, stop, stop that flow!.」Astringents also cause your lips to pucker naturally, and cause a「dry sticky」mouth.
　TAN-colored is derived either from the color of diluted feces in diarrhea, or, the color of a loincloth so permanently stained, or, perhaps the color of unripe persimmons having the same astringent taste being described by this glyph, and unripe persimmons are used to stop diarrhea, with tannins.
　You can guess yourself why the associated meaning of TARDY applies, as in a person may have been delayed by a messy bowel movement or two, or three for that matter. HESITANT, RELUCTANT is also obvious, as one doesn't normally jump with both feet into anything when nursing a severe case of the runs, nor to eat anything known to be an ASTRINGENT, not to mention reluctance for having one's feet bones mashed, one foot at a time.
　Meaning of REFINED TASTE or REFINEMENT probably is associated with being「tight-assed with stiff upper lip, orally and rectally puckered all the time, anal retentive」without relief or relaxation. It has been suggested as well that there is an association at times between the REFINED TASTES of rich foods and loose stools, cause one to keep one's anus puckered to avoid an accidental discharge or inappropriate flatulence with loose stool, a cause of regret.
