adquiridas

Adquiridas is the feminine plural form of the Spanish adjective adquirido, meaning obtained, acquired through experience, effort, or external factors, and not innate. It agrees with feminine plural nouns, as in habilidades adquiridas or infecciones adquiridas. The term is commonly used to contrast with concepts such as lo que es innato, congénito, or natural.

In medical and biological contexts, adquisidas is used to distinguish conditions or factors learned or contracted after birth from inherited or congenital ones. For example, inmunidad adquirida refers to the adaptive immune response developed after exposure to pathogens, while infecciones adquiridas describes infections contracted during life, including nosocomial (hospital-acquired) infections. En otras expresiones clínicas, enfermedades adquiridas o rasgos adquiridos indicate traits or illnesses developed rather than inherited.

Beyond medicine, adquisidas appears in everyday language to denote knowledge or abilities obtained through study and experience, such as conocimientos adquiridos o habilidades adquiridas. In a legal or formal sense, derechos adquiridos refer to rights that have been obtained and are protected by regulation or precedent, as opposed to derechos que podrían obtenerse in the future.

Etymology traces adquiridas to adquirir, from Latin acquirere, meaning to gain or obtain. The suffix -idas marks feminine plural agreement in Spanish. Overall, adquisidas emphasizes the aspect of acquisition or attainment rather than origin by birth or inheritance.
