学ぶ

From 真似(まな) (mana, “imitating, copying”) + ぶ (-bu, “to seem like, to act like”, verb-forming suffix). Cognate with 学ぶ (manebu).^{[1][2][3][4][5]}

The initial mana might be a phonetic shift from mane, itself the continuative or stem nominal form of classical verb 真似 (manu, “to imitate, to copy”), from 真 (ma-, “true, real”) + 似 (nu, “copy, imitate”, lower bigrade conjugation; not attested in isolation).

First cited in the Nihon Shoki of 720.^[2]

The ぶ (-bu) suffix usually conjugated with the upper bigrade pattern (上(かみ)二(に)段活用(だんかつよう) (kami nidan katsuyō)), and manabu conjugated this way until the early Heian period (early 800s). Starting from the mid-Heian (roughly the 900s or 1000s), manabu shifted to conjugate using the classical yodan pattern, the precursor to the modern godan conjugation (五段活用(ごだんかつよう) (godan katsuyō)).^[2]
