Programming languages converge on the same words
Add up every language's vocabulary and you'd expect a huge total. You don't get it — because each new language is mostly words the others already use. The gap between the two lines is how alike code is.
160,037
morphemes if languages didn't overlap (naïve sum)
39,664
morphemes that actually exist (unique union)
75%
of every new language's vocabulary is already known
Every number here is computed from the live NADA pipeline — nothing is hand-typed.
