observatorioihin

Observatorioihin is the illative plural form of the Finnish noun observatorio, meaning “to the observatories” or “into the observatories.” The term is a loanword from Spanish observatorio, which Finnish uses to refer to astronomical observatories as well as other kinds of observatories.

Morphology and usage notes: In Finnish, illative indicates direction toward something. The plural illative suffix -iin is attached to the base form to produce observatorioihin, signaling movement toward multiple observatories. The corresponding nominative plural is observatoriot, and the singular illative would be observatorioon (to the observatory). Observatorioihin is thus used when a verb expresses going to or entering more than one observatory.

Context and style: Observatorioihin appears in scientific, educational, or general prose contexts where Finnish speakers discuss activities involving multiple observatories, such as research expeditions, collaborations, or visits. Because observatorio is a borrowed term, it may be more common in technical writing or in contexts referencing specific observatories, while more general Finnish terms like tähtitieteellinen observatorio or observatorioid may also be used.

Examples: Tutkijat suuntasivat observatorioihin tutkimaan uutta teleskooppia. He matkustivat observatorioihin osana kansainvälistä yhteistyötä. In these sentences, observatorioihin marks movement toward several observatories.
