amplituudilisele

Amplituudilisele is a term that appears in the Estonian language as a grammatical inflection of the adjective *amplituudiline*, meaning “related to amplitude.” In Estonian noun–adjective agreement, the dative form *amplituudilisele* is used when addressing or referring to a specific object in the dative case. For example, one might say “ma arvan amplituudilisele mängul” to mean “I am thinking about the amplitude of the game,” where *amplituudilisele* modifies *mängul* in the dative.

Beyond its grammatical function, the root word *amplituudiline* is employed in scientific contexts within Estonian to describe phenomena involving amplitude—such as oscillations, wave functions, signal strength, and other measurable magnitudes that have a maximum extent. In physics literature, one might encounter phrases like *amplituudiline spektri* to denote the amplitude spectrum of a signal.

The use of *amplituudilisele* in everyday Estonian is relatively rare, mainly restricted to technical writing or specialized dialogue where precise grammatical case is required. The morphological structure of the term follows standard patterns of Estonian adjective declension: nominative *amplituudiline*, genitive *amplituudilise*, dative *amplituudilisele*, and so on.

Because of its specialized nature, the term does not have widespread recognition outside of Estonian-speaking scientific or linguistic communities. Nevertheless, it serves as an illustrative example of how English-derived scientific terminology is adapted and inflected within a highly agglutinative language structure.
