félnyolcas

Félnyolcas is a term in the Hungarian language that is rarely attested in standard usage and is mainly found in dialectal, historical, or field-specific texts. The form is a compound of fél ('half') and nyolcas (derived from nyolc, eight, used in ordinal form to mean 'eighth' or, in some contexts, 'octave'). Because of this, the literal sense can be read as "half of an eighth" or "half an octave," but there is no single, widely accepted definition across domains.

In practice, the sense of félnyolcas is context dependent. In musicology, it could be described as an informal or approximate notion related to a pitch interval near half an octave, though this is not standardized. In linguistic or dialect documentation, it may appear with domain-specific meanings that are not transferable beyond the local tradition. Because reliable, comprehensive definitions are lacking, most references treat félnyolcas as a lexical curiosity or a note on the way the components fél and nyolcas combine in certain regional phrases rather than as a fixed technical term.

When encountered in texts, readers are advised to check the surrounding context or consult local dictionaries and field-specific works for the intended meaning.
