Coming and Going

Five verbs of motion — the legs of every sentence. 行く (iku, to go) and 来る (kuru, to come) are the basic pair (来る conjugates irregularly), 帰る (kaeru, to return home) sends you back, and 歩く (aruku, to walk) / 走る (hashiru, to run) set the pace.

来 is く.る (irregular: 来ない こ.ない, 来た き.た) — its readings shift with the conjugation. 行 is い.く (and コウ in 旅行, ギョウ in 行列). 帰 is かえ.る; 歩 ある.く (ホ in 散歩); 走 はし.る (ソウ in 走者).
