coincidente

Coincidente is an adjective used in Spanish and Portuguese to indicate that something coincides with something else: it happens at the same time, occupies the same position, or shares a common characteristic. In everyday language, it can describe temporal coincidences (fechas o eventos que coinciden), spatial coincidences (dos objetos que ocupan el mismo lugar) or data-related matches (valores que coinciden). The related noun coincidencia (Spanish) or coincidência (Portuguese) denotes the phenomenon of coincidence or a particular coincident occurrence; the English term is coincidence.

In technical contexts, coincidente appears in phrases such as puntos coincidentes (points with identical coordinates) or líneas coincidentes (lines that lie on top of each other). In statistics or data analysis, it can describe equal values, matched samples, or overlapping signals. The sense is typically that two or more things match or meet exactly rather than only approximately.

Etymology: the adjective derives from the verb coincidir, which in turn comes from Latin coincidere, meaning to fall together, formed from con- plus incidere or a related root. The word spread into Spanish and Portuguese with similar meanings.

Notes: In disambiguation, coincidencia is the common noun; coincidente may appear in grammatical or scientific contexts, but everyday usage more often uses coincidencia and coincidir.
