「ござる」「為さる（なさる）」「下さる（くださる）」「いらっしゃる」「おっしゃる」呢五個詞後邊跟住「ます」嘅時候，連用形變成「～い」呢一點同通常五段活用動詞唔同。此外、除「ござる」以外嘅四個詞命令形全數變做「～い」。因此呢五個詞有時被稱為現代文嘅ラ行特別活用動詞。雖然「御座る（ござる）」嚟自「ござ」＋「あり」，「おっしゃる」嚟自「仰せ」＋「あり」，但係相對於古文嘅ラ行変格活用當中終止形同連用形同形嘅特徵，ラ行特別活用嘅特徴係連用形同命令形同形。呢一點表明呢啲詞並非古文嘅ラ行変格活用。
"ござる", "为さる(なさる)", "下さる(くださる)", "いる(くださる)", "いよ(くださる)", "いる(くっしゃる)", "おっしゃる", "おっしゃる", "いい", which is different from the usual five-paragraph active verbs. In addition, all four words except "ござる" have been changed to "~い". Therefore, these five words are sometimes referred to as the ラ行 of modern Chinese, and the verbs are particularly used. Although "御座る (ござる)" comes from "ござ" + "あり", and "おっしゃnaughty" comes from "仰せ" + "あり", in contrast to the characteristics of the use of the ancient text ラ行変格 in which the termination of the form is the same as the form of the same form, the special feature of the use of the ラ行 is that the form of the command is the same form. This indicates that these words are not used in ancient texts.
