Etymology: The plural form of "mouse" as "mice" comes from a fascinating pattern in English known as an irregular or strong plural. Unlike the regular addition of -s or -es to form plurals, some English words, especially those inherited from Old English, change their internal vowel to indicate the plural. This process, called "i-mutation" or "umlaut," was a common feature in the Germanic languages and survives in a handful of words today. Originally, the Old English word for "mouse" was "mūs," pronounced roughly like "moos," and its plural was "mȳs," where the vowel shifted from a long "u" sound to a long "y" (a fronted vowel sound). This vowel change signaled the plural form without adding an ending. This pattern was widespread in Old English and other Germanic tongues but gradually faded as English evolved, making "mouse" to "mice" one of the few remaining examples of this ancient linguistic feature. The plural "mice" was well established in Middle English by the 12th and 13th centuries, maintaining the vowel change from the singular. Over time, the pronunciation shifted to the modern /maɪs/, with the diphthong "ai" reflecting changes in vowel sounds that occurred during the Great Vowel Shift between the 15th and 18th centuries. Despite many English plurals becoming regularized, "mice" remained as a linguistic relic that points back to English's Germanic roots. This irregular plural stands alongside other words like "foot" to "feet" and "goose" to "geese," all preserving traces of the older system of plural formation. Such words often catch the eye of learners because they break the usual rules, but they offer a window into the history of English and how it has transformed over the centuries.
