Surface Forms
Morphology
The compound combines 'delta' (triangle-shaped) + 'wing' (aircraft lifting surface) to denote a triangle-shaped airplane wing; this meaning is directly and literally derivable from the constituents. Although somewhat technical, the formation is compositional and parallels similar compounds in other languages, so a B1 learner who knows the parts should understand it.
Etymology
Delta wing comes from the Greek letter delta, which is a 'triangle', and the word wing, because the wing is shaped like a triangle. That's why the name refers to triangle-shaped airplane wings used to help very fast planes fly better and stay steady.
