• Aliquot — The feminine form of the term aliquot; an exact subdivision of a whole that is contained within it a determinate and integer number of times, leaving no remainder. In analytical laboratory chemistry, it represents a volumetric liquid or solid portion precisely extracted from a homogeneous sample, while in the legal field it defines an ideal, abstract, and fixed share of a common patrimony, usually expressed as a fraction or percentage.
• Anaperi — A niche zoological term or scientific archaism used to describe a category of organisms, insects, or larvae characterized by the complete absence or structural regression of hairs, spikes, or sensory bristles on the body surface. In older comparative anatomy studies, the word served as a taxonomic descriptor to differentiate completely smooth specimens from those covered with functional hairs or cilia.
