substitution
One for another
Substitution is the act of replacing one thing with another: The coach made a substitution in the second half.
In cooking, a substitution swaps one ingredient for another: Use applesauce as a substitution for oil.
In mathematics and logic, substitution replaces variables with values or expressions.
The word emphasizes the exchange itself—something goes out, something equivalent goes in.
