raadiulise

Raadiulise is a rarely attested Estonian adjective that would denote something pertaining to radio if formed from the noun raadio. It is not listed in major Estonian dictionaries and has limited attestations in published material. As such, it is best understood as a coinage or hypothetical derivation rather than an established term. In linguistic discussions, raadiulise is often cited as an example of how Estonian can form adjectives from nouns by attaching the suffix -lise, though its usage in actual prose remains uncommon.

In practice, speakers needing to express “radio-related” typically rely on standard compounds built with raadio or on domain-specific terminology, depending on context. For example, they might use established phrases referring to radio technology, radio communication, or radio waves, rather than this ad hoc form. If encountered in fiction or language-learning materials, raadiulise can convey a technical or pseudo-scientific flavor, but readers should treat it as a neologism rather than a normative term.
