sound
1. {audio}.
2. An {inference system} A is sound with respect to
another system B if A can only reach conclusions which are
true in B. A {type inference} system is considered sound with
respect to a {semantics} if the type inferred for an
expression is the same as the type inferred for the meaning of
that expression under the semantics.
The dual to soundness is {complete}ness.
