Japanese tatsu is “built, established;” tatsu is also “rise, stand up.” As usual, the צ Tsadi/TS is lasting, while the ב Bhet/BH drops. The S seems to drop too, In Japanese stand-upright terms like tate (height), and tateru (build, construct, establish).

Thousands of reverse synonyms are out there, not seen because of simple Grimm’s Law letter shifts. For example, sturdy, enduring fricative-bilabial words like ESTABLISH, STUB, STUBBLE, STUBBORN, and STIFF are the same theme as the reverse: bilabial-fricative words like FAST (stuck), POST, VESTED, VESTIGE. But only FAST and STIFF reverse the same letters.
