insincera

Insincera is the feminine singular form of the adjective meaning insincere, used in several Romance languages, notably Italian, Spanish, and Portuguese. It describes someone or something that lacks sincerity, candor, or truthful intention. As an adjective, insincera agrees with the gender and number of the noun it modifies.

In Italian, insincera accompanies feminine nouns, for example una persona insincera or una dichiarazione insincera. The masculine counterpart is insincero, and the plural forms are insincere (feminine) or ins inceri (masculine) depending on gender, with standard agreement rules applying.

In Spanish and Portuguese, insincera performs a similar role. In Spanish it is the feminine form of insincero, used with feminine nouns (e.g., una afirmación insincera). In Portuguese it is the feminine form of insincero (e.g., uma desculpa insincera). The masculine equivalents are insincero, insincero plural for masculine and insinceras for feminine plural.

Etymology generally traces insincera to the Latin sincerus meaning pure or sound, with the negative prefix in- producing insincera’s sense of not sincere. A popular but uncertain folk etymology links sincerity to “without wax” (sine cera) in ancient contexts, though this connection is not definitively established.
