vibratsioonilisi

Vibratsioonilisi is a form of the Estonian adjective vibratsiooniline, used to describe things related to vibration. Specifically, vibratsioonilise forms occur in the partitive plural, which is used when referring to an indefinite amount or extent of multiple items. In practical terms, vibratsioonilisi describes attributes of several objects or phenomena in a non-specific quantity.

In Estonian grammar, adjectives agree with the nouns they modify in number, case and definiteness, but not gender. The nominative singular form is vibratsiooniline, the partitive plural form is vibratsioonilisi, and there are other inflected forms for different cases and numbers. The use of vibratsioonilisi typically appears in technical, scientific, or descriptive prose where researchers discuss multiple vibrational properties or effects without naming a definite set.

Common contexts include physics, engineering, acoustics, and materials science, where researchers address how systems behave under vibrational influence. For example, one might write: vibratsioonilisi omadusi iseloomustavad ... (the vibrational properties are characterized by ...), or vibratsioonilisi mõjusid tuleb arvesse võtta (the vibrational effects must be taken into account). These phrases illustrate how the form functions to link a plural noun in the partitive case with the concept of vibration.

As a grammatical form, vibratsioonilisi is not a standalone lexical item but a specific inflection of vibratsiooniline. Learners should recognize it as part of Estonian adjective inflection patterns and use it when the noun it describes is in the partitive plural.
