Morphology

Jaculus + Jaculus

The phrase is a Latin binomial (genus + species) where both constituents are the same word; if a learner knows that 'Jaculus' names the jerboa genus, they can infer this refers to a particular species. However, understanding that repetition is a taxonomic naming convention requires specific knowledge of scientific binomial nomenclature rather than ordinary compositional meaning, so the connection is only partially transparent to an average B1 learner.

Etymology

Jaculus jaculus comes from the Latin word jaculus, which means 'dart' or 'javelin'. People gave this name because the tiny desert rodent jumps quickly and straight like a thrown dart, so today the name refers to that small jumping animal.
