This is one question that boggles the minds of many learners of the Swedish language (as well as the other Nordic languages). Why doesn’t ‘hand’ just become ‘hander’ or ‘handar’ in plural?

The answer to this lies in a major change that occurred throughout Germanic Europe in the Early Middle Ages (which in Scandinavia was the middle of the Iron Age, 450~500 AD). The process is known today as the i-omljud in Swedish (in English the Germanic umlaut, i-umlaut, or i-mutation). What happened during this change was that an unemphasized i (prounced like ‘ee’ in modern English) in a word brought emphasized back vowels (vowels produced in the back of the mouth: a, o, u) forward, closer to i. For example, what you’re here to find out:

– The plural of hand in Old Norse was handiar. But since it is natural for human beings to simplify things, people began to say hændar (/´hændər/), combining the a with the i, creating a new sound, æ (pronounced similarly to the a in hat). From there, the æ as well as the ar at the end became more and more weakly pronounced, leading to its modern pronunciation, /´hɛndər/, orthographized as händer. The singular form, hand, however, remained the same because it lacked an i to change it.

The i-omljud also affected the other back vowels, o and u. Before this process, Old Norse only had five vowels: a, e, i, o, and u, like the rest of the Indo-European languages of that time. After the i-omljud, though, three more vowels had developed, namely y (what you get when you combine i and u), æ (i and a combined, as shown above), and ø (from i and o). The letters æ and ø were used when the Latin alphabet was first adopted but were replaced by the Low German ä and ö toward the end of the Middle Ages (in Sweden, 1050~1520 AD). Previously, Swedish was written completely in runes.
