πλευρή (alternative Ionic)

→ Medieval Latin: pleura

→ English: pleura

→ French: pleura

→ Italian: pleura

→ Portuguese: pleura

→ Spanish: pleura

Of uncertain origin. The traditional connections with πλάξ (pláx, “flat object, plate”) (< *plk-) and παλάμη (palámē, “palm”) (< *plh₂-em-eh₂-), via an unattested *πλῆ-ϝαρ (*plê-war), suggest a derivation from Proto-Indo-European *pleh₂- (“flat”). The semantics seem reasonable; however, the morphological formation is unclear.
An alternative theory, deriving the word from a Proto-Indo-European *pnew-reh₂, from *pnew- (“to breathe”), would leave the lambdacism (ν (n) > λ (l)) unexplained (although compare πλεύμων (pleúmōn, “lung”)), in addition to being semantically farfetched (the "lung membrane" meaning appears to be a much later innovation in the English borrowing that was never present in Greek), particularly when compared to the connection with *pleh₂-.

(geometry) A line that forms the side of a triangle or other two-dimensional figure.

A side of a rectangle; (mathematics) one factor of any product.

350 BCE – 250 BCE, Euclid, Elements 8.17.11

A side of a square of a cube; (mathematics) a root of a square of a cubic number.

→ Serbo-Croatian:
Cyrillic script: ђу̀нија

→ Classical Syriac: ܓܘܢܝܐ (gōnyā)

From a derivative of γόνυ (gónu, “knee”), ultimately from Proto-Indo-European *ǵónu (“id”). The long ω (ō) is from the regular Doric development of an unattested *γονϝ-ία (*gonw-ía), as the paradigm of *ǵónu shows no lengthened grade (thus precluding a derivation from such an ablaut), while most mathematicians in Greek antiquity (who were most likely responsible for the word's formation) were Pythagorean (and thus wrote in Doric).
