Apparently there’s this tatewaku 「竪沸く」and this one 「立枠」which I “tested” and wrote about yesterday . It revealed those wavy lined images seen on kimono, obi, woven and worked also in sashiko and shibori.
To explain a bit, Neki (Neki desu) commented on tate this morning and then for curiosity I went back to Mary Parker’s book and lo and behold there was tatewaku in a different set of kanji: 「竪沸く」- back to the dictionary.
This tate 「竪・たて」is (via Jim Breen):
(1) the vertical; height; (2) front-to-back; length; (3) north-to-south; (n,adj-no) (4) vertical (relationship); hierarchy; (n) (5) (See 経糸・たていと) (weaving) warp.
This waku・沸く・わく means “) to grow hot (of water, etc.); to boil” – think steam – vertical steam – rising steam, hence, that rising steam pattern.
So, to test it out, I input the kanji on Google search and went for the images – they were mostly practical images having literally to do with building, engineering…that kind of thing, but there were a few with that ‘rising steam’ pattern.
With this 「立枠」kanji I had more textile related results. Who can say? It’s an ancient language and languages are always changing and then again, there are so many different contexts.
