What does tenuis mean?
Tenuis is a learned English adjective borrowed from Latin, meaning thin, slender, or delicate. Its modern use is uncommon outside formal scientific and taxonomic descriptions, where it can characterize a species, organ, or other structure as slender or slight. In writing such as a species description, the term may be italicized as a taxonomic epithet, so its apparent brevity should not be mistaken for ordinary adjective agreement. Tenuis also carries associations of fineness and delicacy rather than the general idea of reduced size. It should not be confused with tenuous, which usually describes something so slight as to be barely perceptible or lacking in substance; tenuis is more directly an anatomical or taxonomic descriptor. Related English words include tenuous, tenuity, attenuate, and attenuation, all reflecting the Latin idea of thinness. Tenuis is therefore chiefly useful to readers of biology, anatomy, and Latinate scholarship, though its precise, formal character makes it memorable in general use as well.

"The leaf is tenuis, tapering gradually toward the tip."
"The entomologist described the beetle as tenuis, noting the narrowness of its antennae."
"In the Latin diagnosis, the author contrasted the tenuis body with the broader form of the related species."
In taxonomy, tenuis is a compact way to announce that a specimen is slender—and its relatives tenuous and tenuity carry the same Latin root.
