詹憲慈《香港中文大學出版社·廣州語本字·394 打到褪》原文：

到褪者倒退也俗讀到若倒讀褪若吞上聲沈與求詩十篙八九褪韻會褪吐困切

試解：

• 到褪¹者，倒退也。俗讀到若倒。讀褪若吞，上聲。 🗣
• [北宋] 沈與求²詩《龜溪集》十篙八九褪³。
• [元]《古今韻會舉要》褪：吐困切

翻書仔注：

據北京《新華字典》「褪」乃「退」之後起分化字。無對應之 [北宋]《廣韻》韻目。[元]、[明] 韻書俱注「吐困切」⁴。查《韻典網》「吐困切」：

• 八震韻目
• 褪字頭
• 明代擬音⁵ IPA: t’ǔn 去聲 (《韻典網》用舊制標 IPA: tʰǔn)
• 中大字庫⁶ IPA: t’ɐn3 隂去聲

隂去聲合今香港讀音。詹氏原文謂 “讀褪若吞，上聲” 已不合現代香港音。「褪」本義卸衣。《新華字典》又謂解退卻⁷。[清]《儒林外史》有 “匡超人就褪下幾步，到那童生跟前…” 一段。「褪」解後退為引伸用法。詹氏原文例詞 “打到褪” 之「褪」，合音合義，可為本字之選。

Synopsis:

IPA: t’ɐn3 is a Cantonese colloquial sound which most Cantonese speaker will use to mean back up or reverse but few know how to write. The Original Character is 褪 as per the book. The word was derived from an older word 退 with similar meaning but pronounced differently. The nominal meaning of 褪 is to undress or to fade as in colour fading. It however still retains the meaning to back up and reverse as in the older character from which it came.
