This paper examines the distribution of English self-pronouns (himself, herself, etc.) in contrast with personal pronouns. We confirm that there are factors affecting the acceptability of self-pronouns at the syntactic, semantic, and discourse levels, and devise a Principle A with three distinct clauses to account for all of them. Each clause is crucially ordered with respect to the others, with syntax taking precedence over semantics, which in turn takes precedence over discourse constraints.
