Lim Hiong Seng, Handbook of the Swatow Vernacular (1886)
“ Lióu [1] 了 (finish) can only be used to subjects being spoken of, and cannot be used in asking questions, viz.— 伊來了 I lâi--lō He has come. 阮知了 Ún tsai--lō We have known. 因到了 In kàu--lō They have arrived. Chiàn 正 (just) and 識 pat (ever) can be used both to questions and answers, viz.— 伊正來 I chiàn-lâi He has just come. 爾此時正來 Lṳ́ chi-tsûn chìan-lâi? Have you just now come? 爾昔識來此處否 Lṳ́ tsá pat-lâi--chié mē? Have you ever been here before? 我昔不識來此處 Uá tsá m̄-pat lâi--chié I have never been here before. ”
