Etymology: "Zwei" is the German word for "two," and it is one of the few numerals that English shares almost unchanged. Its English cognate is "two," and the pair descends from the same Proto-Germanic root, reconstructed as "twai," which also gave Old English "twa" and Old Norse "tveir." The German form kept the Proto-Germanic vowel shape more closely in the neuter and in compounds, while English "two" was shaped by its own sound changes, so a reader can see the family resemblance without any help from a dictionary. Because German and English both inherited the number from one ancestor, "zwei" is not a loanword and has no Latin or Greek behind it, which surprises many English speakers who expect German numerals to be borrowed from other languages. The same root also appears in "twin," "twelve," and "twenty," showing how a single ancient word for "two" spread through the English vocabulary in compounds.
