| Variable (-conversion) | x | A character or string representing a parameter or mathematical/logical value. |
| Substitution ( reduction) | (λx.M)(value to be bound to x) | This expression specifies how function is defined by replacing values of bound variable x in the lambda (λ) expression M. |
| Composition (-reduction) | (M N) | Specifying the sequential composition of multiple lambda expressions such as M and N. |
