Semantogram

"the majority of Jurchen signs, which included both semantograms and phonograms, were inventions."

One could write OJ namyi ‘wave’ with the sinograph for a Chinese morpheme of similar meaning: 波 EMC *pa ‘wave.’ 波 *pa ‘wave’ would then be a semantogram for OJ namyi, serving as a translation of OJ namyi without representing its sound.
