Certain nouns in the English language exhibit a unique characteristic where their singular and plural forms are identical. This phenomenon contrasts with the typical convention of adding an “s” or “es” to create plural nouns. Examples include “sheep,” “deer,” and “aircraft.” This quirk often leads to confusion among learners of English, as they expect distinct singular and plural forms for most nouns. However, it underscores the rich tapestry of English and its exceptions, which stem from its diverse linguistic roots and evolution over time.
