 An *output type inference* is made *from* an expression `E` *to* a type `T` in the following way:
 
-- If `E` is a tuple expression with arity `N` and elements `Eᵢ`, and `T` is a tuple type with arity `N` corresponding element types `Tₑ` or `T` is a nullable value type `T0?` and `T0` is a tuple type with arity `N` that has a corresponding element type `Tₑ`, then for each `Eᵢ` an output type inference is made from `Eᵢ` to `Tₑ`.
+- If `E` is a tuple expression with arity `N` and elements `Eᵢ`, and `T` is a tuple type with arity `N` with corresponding element types `Tₑ` or `T` is a nullable value type `T0?` and `T0` is a tuple type with arity `N` that has a corresponding element type `Tₑ`, then for each `Eᵢ` an output type inference is made from `Eᵢ` to `Tₑ`.
 - If `E` is an anonymous function with inferred return type `U` ([§12.6.3.13](expressions.md#126313-inferred-return-type)) and `T` is a delegate type or expression tree type with return type `Tₓ`, then a *lower-bound inference* ([§12.6.3.10](expressions.md#126310-lower-bound-inferences)) is made *from* `U` *to* `Tₓ`.
 - Otherwise, if `E` is a method group and `T` is a delegate type or expression tree type with parameter types `T₁...Tᵥ` and return type `Tₓ`, and overload resolution of `E` with the types `T₁...Tᵥ` yields a single method with return type `U`, then a *lower-bound inference* is made *from* `U` *to* `Tₓ`.
 - Otherwise, if `E` is an expression with type `U`, then a *lower-bound inference* is made *from* `U` *to* `T`.
