reeglipärased

Reeglipärased is a term used in Estonian grammar to describe nouns that follow the standard rules of declension. In Estonian, nouns change their endings based on their grammatical case and number. Nouns that adhere to these predictable patterns are considered reeglipärased. This contrasts with ebareeglipärased, or irregular nouns, which have unpredictable or exceptional declension forms. Understanding the concept of reeglipärased is fundamental to mastering Estonian grammar, as it allows learners to anticipate how most nouns will change in different contexts. For example, the genitive singular of most nouns ending in -a, -e, or -i is formed by adding -i, and the partitive singular is often formed by adding -t. These are typical reeglipärased patterns. Conversely, certain older or more commonly used nouns might exhibit ebareeglipärased forms, requiring memorization. The majority of Estonian nouns, however, fall into the reeglipärased category, simplifying the learning process for those studying the language.
