mo, mo yo, mo ya, shi mo, ya shi, yo shi, are all interjectional expressions, not mere fill-gaps, variously emphasizing or calling attention to the meaning of the words, &c., they are attached to.
Honour-Words. Such are ohomi (exalted, grand), as ohomi kami, ohomi uta, ohomi ma; mi, as mikokoro, miko, mi-hakashi, mi-keshi, mi-nemasu (His godship the God, His Majesty’s song, His Majesty’s horse, my lord’s meaning, my lord the Son (Prince), girt by my lord, my lord’s garments, my lord sleeps).
Other honour- (or praise-) words are:—
oho (great), futo (stout), toyo (rich), o (for oho) as in obito, omi (court officials); mi, ma, mo, sa, oho also denote excellence (εὐ), wo may be antithetic to oho, or it may be a term of intimacy, a sort of diminutive of endearment.
