The I-Mutation/I-Umlaut

In English linguistics, the phenomenon known as I-mutation or I-umlaut is a pivotal historical sound change. This modification affected the way in which vowels were pronounced in certain contexts, particularly when a high front sound like /i/ or /j/ followed in the next syllable.

For instance, the transition from Old English to Middle English saw words like “man” transform in the plural to “men” through the process of I-umlaut. Here’s a simple representation:


Other examples include:

  • foot changed to feet
  • tooth changed to teeth

These shifts demonstrate how the presence of a subsequent /i/ or /j/ sound in a word influenced the alteration of the preceding vowel sound. This linguistic adjustment is critical to understanding the irregular nature of certain plural forms in the English language.

The I-umlaut has its roots in the ancestral languages of English, tracing back to a time when certain vowel shifts were common to facilitate smoother transitions between sounds. Below are a few examples of how words have transformed over time due to this process:
