inexplicada

Inexplicada is the feminine singular form of the past participle of the Spanish verb explicar when used as an adjective. It means “not explained” or “unexplained” and agrees with feminine nouns. The corresponding masculine form is inexplicado, and the plural forms are inexplicadas and inexplicados.

Etymology and usage notes: The word is built from explicAR with the negating prefix in- and the gendered, participial ending -ada (feminine) or -ado (masculine). It is commonly employed in formal or analytic writing to characterize information, phenomena, or causes that have not been fully clarified. While inexplicable is more widely used in everyday Spanish as a synonym, inexplicada emphasizes the grammatical agreement with a feminine noun.

Typical contexts: Inexplicada appears in scientific, journalistic, or analytical prose to indicate an unresolved aspect. Examples include “la causa inexplicada de la caída” (the unexplained cause of the fall) or “la anomalía inexplicada observada en el experimento” (the unexplained anomaly observed in the experiment). It can also occur in broader discussions where explanations are lacking or insufficient.

Relation to related terms: Inexplicada is a gendered form of a broader set of negated participial adjectives formed with in- plus -ado/-ada. It is distinct from inexplicable, which remains invariable in certain uses in Spanish but may be preferred in less technical language. In everyday style, writers often opt for phrases like “no aclarado” or “aún por explicar” depending on context.
