sonecznej

Sonecznej is a term that appears in some texts as a non-diacritic variant of the Polish word słonecznej, the feminine genitive (and dative) form of the adjective słoneczny, meaning sunny or solar. In standard Polish orthography the correct form is słonecznej, with the diacritic l (ł) and the ending -ej. The appearance of sonecznej without diacritics is not considered correct in normative Polish and is more often encountered as a transcription error, OCR artifact, or informal reproduction.

In Polish grammar, adjectives agree with the gender, number, and case of the nouns they describe. For a feminine singular noun in genitive or dative, the expected form is słonecznej. Examples include phrases like pogody słonecznej (of sunny weather) or okolicy słonecznej (in the sunny area). When texts are converted to ASCII or stripped of diacritics, the resulting forms are sometimes distorted, potentially yielding nonstandard spellings such as sonecznej or slonecznej, depending on the process used.

Because sonecznej is not a standard spelling, it does not have an independent entry in Polish dictionaries. When encountered, it should generally be treated as a misspelling or a nonstandard transliteration of słonecznej. Correct usage depends on the noun and case; the underlying meaning remains tied to sunshine or solar qualities.
