indeklinatiivsed
Indeklinatiivsed, also known as indeclinable words, are a category of words in the Estonian language that do not change their form based on grammatical case, number, or gender. These words typically include proper nouns, foreign words, abbreviations, and certain technical terms. Proper nouns, such as names of people, places, and organizations, retain their original form regardless of the context in which they are used. Foreign words, when adopted into the Estonian language, often remain indeclinable to preserve their original meaning and pronunciation. Abbreviations, such as "USA" for the United States of America, also fall into this category, as they are typically written in uppercase letters and do not change form. Technical terms, especially those from specific fields like science or technology, may be indeclinable to maintain their precise meaning and to avoid confusion. The indeclinable nature of these words helps to maintain clarity and consistency in communication, especially in contexts where grammatical agreement is not necessary or would be impractical.
