Etymologies
- From Ancient Greek δυσπρόσιτος (dusprositos, "hard to get"). (Wiktionary)
- New Latin, from Greek dusprositos, difficult to approach : dus-, dys- + prositos, approachable (from prosienai, to approach : pros-, toward + ienai, i-, to go; see ei- in Indo-European roots). (American Heritage® Dictionary of the English Language, Fourth Edition)
