english: Over time, even as fewer literate people knew Latin, the "b" was kept because it marked important, meaningful connections to other related words, like "dubious" and "indubitalbly," which were subsequently borrowed into English from the same Latin root, "dubitare".
non_english: Na verloop van tijd kenden steeds minder mensen Latijn, maar hield men de 'b', omdat deze belangrijke connecties had met aanverwante woorden, zoals 'dubious' (twijfelachtig) en 'indubitably' (ongetwijfeld), die zijn overgenomen in het Engels vanuit dezelfde Latijnse stam: 'dubitare'.
