1990年之前臺語用字仍屬嘗試期，用字極之唔統一，有人創造新字，亦有語文專家考證本字，再加上原有嘅傳統用字、華文用字，可以話係百花齊放。進入1990年代之後，由於臺語文作家互相觀摩學習嘅結果，用字漸趨統一，奇怪嘅新創字、古字逐漸銷聲匿跡。新嘅臺語文字，一方面有所傳承，亦有所創新，但係總係離唔開「通俗性」、「語源可靠性」、「音義系統性」三大原則。其次係漢字同拼音唔再自成系統，而有合流現象，即係所謂「有音無字」嘅詞素用拼音字表示，嘗試以拼音字做文字嘅一部分，臺語文學嘅用字，逐漸朝向統一嘅道路邁進(侯俊榮 nd；楊允言 1993)。
Before 1990, the use of Taiwanese words was still in the trial period, and the words were very inconsistent, some people created new words, and there were also language experts who verified the original words, plus the original traditional words and Chinese words, it can be said that a hundred flowers are blooming. After entering the 1990s, as a result of Taiwanese writers observing and learning from each other, the use of characters gradually became unified, and strange new and ancient characters gradually disappeared. On the one hand, the new Taiwanese script has been inherited and innovated, but it is always inseparable from the three principles of "popularity", "etymological reliability", and "phonetic systematization". The second is that Chinese characters and pinyin are no longer self-contained, but have a confluence phenomenon, that is, the so-called "sound without words" morphemes are represented by pinyin characters, and attempts are made to use pinyin characters as part of the text, and the words used in Taiwanese literature are gradually moving towards the road of unification (Hou Junrong n.d., Yang Yunyan 1993).
