The english sentence that replaces the programming language statement:

   for N = Start to End do

is:

   For every 'N' from Start to End, do what follows.

Notice that the computer language follows as closely as possible the 
syntax of english.

Wording it to put 'From' at the beginning we would end up with:

   From Start to End, putting the value in 'N', do what follows.

and hence (perhaps):

    from Start to End into N do

Putting the variable (N) after a 'from' wouldn't scan properly.

Perhaps a 'with each' statement would be a better (hypothetical) choice?:

    with each N from Start to End do
