Etymology (EN): From L. conspicuus “visible, open to view,” from conspicere “to look at, observe, see, notice,” from → com-, intensive prefix, + specere “to watch, look at,” → spectrum.

Etymology (PE): Hoveydâ “conspicuous, manifest, evident,” variant vidâ, probably related to Av. hu-vaēiδiia- “good knowledge, well-known,” from hu- “good, well,” → eu-, + vaēiδiia- “knowlege, known.”
