(linguistics, grammar) pro-verb, pro-form of a verb

doの用(よう)法(ほう)の最(さい)後(ご)は【代(だい)動(どう)詞(し)】です。代(だい)名(めい)詞(し)の動(どう)詞(し)版(ばん)。英(えい)語(ご)は同(おな)じ単(たん)語(ご)を何(なん)回(かい)も使(つか)うのを嫌(きら)うので、動(どう)詞(し)も2(に)回(かい)目(め)はdoにしてしまうことがよくあります。

do no yōhō no saigo wa【daidōshi】desu. Daimeishi no dōshi ban. Eigo wa onaji tango o nankai mo tsukau no o kirau no de, dōshi mo nikaime wa do ni shite shimau koto ga yoku arimasu.The final usage of do is as ‘pro-verb’, the verb version of a pronoun. Since English doesn't like to use the same word again and again, it is common to use do in place of the verb the second time.
