User:Uno b4/sandbox/Japanese verb conjugations

Verb conjugates are often grouped into consonant-stems (五段動詞), vowel-stems (一段動詞), and action verbs. The plain form of a type I verb has an う u sound (u, tsu, ru, ku, gu, bu, mu, s u ), the ～ます -masu form has an い i sound (i, chi, ri, ki, gi, bi, mi, sh i ), and the negative form has an あ a sound (wa, ta, ra, ka, ga, ba, ma, s a ). The potential form has an え e sound (e, te, re, ke, ge, be, me, s e ) and the volitional form has an おう ō sound (ō, tō, rō, kō, gō, bō, mō, s ō ), so putting these together with the sounds above shows that verb conjugations follow the vowel syllabary of the Japanese character set:　あ a, い i, う u, え e and お o.
