In Gnu Emacs Lisp its name is "elt".

Cheers.

P.S.  To refresh after 40 years:

Go to the "scratch" buffer in Gnu Emacs and enter
    (setq myseq '("a" "b" "c" "d" "e"))
then press C-j to see:
    ("a" "b" "c" "d" "e")
Then
    (elt myseq 3)
which returns:
    "d"
With the cursor over "elt" above enter  C-h f
to see the help for "elt":
    elt is a built-in function in `C source code'.
    (elt SEQUENCE N)
    
    Return element of SEQUENCE at index N.
