I would go and say Fortran is pretty legible because it only has a handful of builtin keywords and none of the fancy stuff alot of other languages have.

Julia has the fancy stuff aswell as being very legible and also having a nice REPL for instant feedback which is usefull for people learning (as well as multiple notebook implementations Pluto.jl or Jupyter) Chapel has even more of the fancy stuff like multiple loop types for different kinds of parallelism which is just wildly cool.
