高 — pictograph of a tall building/tower
高 is a pictograph of a tall structure, likely a watchtower or multi-story gate, with a roof on top, an upper chamber, and a base below. From this concrete image of height it extended to the general meanings 'tall,' 'high,' and figuratively 'lofty' or 'noble.'
尚 — 八 (eight/divide) over 向 (window/direction)
Originally depicted vapor or breath rising and dispersing upward from an opening, suggesting elevation and what is above. From this came the meanings 'still,' 'yet,' and 'to esteem' — what one looks up to. The modern senses of 'esteem' and 'still/yet' both stem from this upward orientation.
