"Eells" is a peculiar word, with a spelling that defies traditional English phonetics. In fact, the pronunciation of "eells" can appear confusing to non-native speakers, as it is pronounced as /iːlz/ (eelz) instead of /iːl/ (eel), which one might expect from its spelling. The added 's' at the end changes the pronunciation of the vowel sound, producing the 'ee' sound that distinguishes it from the singular "eel". Despite its unconventional spelling, "eells" is a legitimate word that refers to multiple eels.
