Kakkos

Kakkos is a transliteration of the Greek word κακός, which means "bad" or "evil." The Greek spelling contains two kappa letters in sequence, and transliterations that preserve this double consonant yield forms such as "kakkos." In English-language texts, the variant "kakos" is also seen, reflecting a more common transliteration of the same word.

In Modern Greek, κακός functions as an adjective describing something of poor quality or morally wrong. It is inflected for gender and number, with forms including κακός (masculine singular), κακή (feminine singular), and κακό (neuter singular), as well as corresponding plural forms such as κακοί, κακές, and κακά. Related terms derived from the same root include κακία (kakia, meaning "malice" or "wickedness").

Beyond its meaning in Greek, "kakkos" appears in onomastic contexts as a surname or part of a family name among Greek speakers and descendants. As a surname, it may be encountered in genealogical or biographical material, but it is not associated with a single widely known figure.

In English-language usage, the term is primarily of linguistic or philological interest, appearing mainly in discussions of transliteration, Greek orthography, or etymology rather than as a common word in everyday speech.
