Góðs is the genitive singular form of the Icelandic adjective góður, meaning “good.” In Icelandic, adjectives decline to agree with the noun they modify in gender, number, and case. The genitive singular forms for masculine and neuter nouns are typically góðs, while the feminine genitive singular is góðrar. This form is used when expressing possession or association, or when the adjective stands with a noun in the genitive case. For example, góðs manns means “of a good man” (or “the good man’s”), and góðs barns means “of a good child.” The feminine form would appear as góðrar in corresponding phrases, such as góðrar konu meaning “of a good woman.”

Etymology and usage context: góður comes from Old Norse góður, itself from Proto-Germanic *gōdaz, and has parallel forms in other North Germanic languages. The genitive góðs is common in formal, archaic, or literary Icelandic, but may still appear in everyday prose in contexts that require a genitive construction.

Notes: góðs is not a standalone noun and should not be confused with guðs, the genitive of guð (god). The two forms are phonologically similar but semantically distinct. In modern Icelandic, góðs mainly surfaces in fixed or stylistic expressions and in grammatically explicit phrases requiring the genitive case.
