Negraising

Negraising, also called neg-raising, is a phenomenon in linguistics where the negation associated with an embedded clause is interpreted at the main clause level. In sentences exhibiting negraising, the negative meaning seems to apply to the overall proposition rather than only to the embedded proposition, often because the negation appears to “raise” to the higher clause.

A classic illustration involves verbs of appearance or perception. For example, in English the sentence John didn't seem to be tall can have a reading equivalent to John seems not to be tall. Similarly, Mary didn't appear to be at the party can be understood as Mary appears not to be at the party. In these cases, the negation outside the embedded clause carries the interpretation that the outer proposition is false or negated, even though the negation is syntactically attached to the embedded clause.

Negraising is most commonly discussed with verbs like seem and appear, and its acceptability can vary by dialect and context. Some environments also show a weaker or ambiguous negraising reading, while others may force a non-raising interpretation where the negation only targets the embedded proposition. The phenomenon has implications for theories of negation, scope, and the interaction between syntax and semantics, and it has been the subject of ongoing debate among linguists, with multiple analyses proposed for how the raised interpretation arises.

Cross-linguistically, negraising behaviors differ. English exhibits robust negraising with certain verbs, but other languages may restrict or pattern differently in how negation interacts with embedded clauses.
