It works both ways in grammar: you can unroll something (with an object), or something can unroll by itself — 'the map unrolled across the table'. That second use, with no object, is common and perfectly natural.
It這個字 works both ways in grammar在文法上兩種用法都有 you你 can unroll something可以unroll某個東西 with an object帶受詞 or something can unroll by itself或者某個東西自己unroll 'the map unrolled across the table'地圖在桌上自己攤開了 That second use, with no object那第二種不帶受詞的用法 is common and perfectly natural很常見也完全自然
The word carries a small sense of ceremony when the thing being unrolled is important — a scroll, a banner, a carpet — because unrolling reveals what was hidden inside. That is why 'roll out the red carpet' and its cousins feel grand.
The word這個字 carries a small sense of ceremony會帶一點儀式感 when the thing being unrolled is important當被攤開的東西很重要時 a scroll卷軸 a banner旗幟 a carpet地毯 because unrolling reveals what was hidden inside因為攤開會揭露原本藏在裡面的東西 That is why這就是為什麼 'roll out the red carpet' and its cousins「roll out the red carpet」這類說法 feel grand讓人覺得隆重
One honest note: for a poster stuck in a tube, English speakers will just as often say 'open it up' or ' it out'. `Unroll` is precise and correct, but it is not the only or even always the most common thing people say. In writing, though, it is the exact word, and exact words are worth having.
One honest note老實說一句 for a poster stuck in a tube對於捲在筒子裡的海報 English speakers英文使用者 will just as often say常常也會說 'open it up'把它打開 or 'flatten it out'把它壓平 `Unroll` is precise and correct精確又正確 but it is not the only or even always the most common thing people say但它不是唯一的說法甚至不見得是大家最常用的說法 In writing在書寫時 though不過 it is the exact word它才是最精準的用字 and exact words are worth having而精準的用字是值得擁有的
core核心畫面
組成un- + roll. Here un- means 'do the reverse of the action' rather than simply 'not' — the same un- as in undo, untie, unpack. 'Roll' traces back through Old French to Latin rotula, a little wheel, from rota, a wheel.
