3. A meteorite characterized by its high metal content, primarily iron, with a minor presence of silicate minerals

Etymology: Oligosiderite is built from two Greek-derived parts. "Oligo-" comes from the Greek "oligos," meaning few or little, while "siderite" joins "sideros," the Greek word for iron, to the suffix that signals a stone or mineral. Put together, the name describes exactly what the object is: a stony meteorite with little of the usual silicate material and a heavy metallic makeup. The pattern is typical of scientific vocabulary, where classical roots are assembled to name a newly classified thing. Meteorite researchers sort these rocks by composition, and the prefix "oligo-" appears in several other technical terms to mean scarce or reduced. The word therefore belongs to a modern classification system rather than to any ancient vocabulary.
