I investigate a diverse set of Czech words of unclear prosodic status. The analysis
reveals that while it is possible to make a clear distinction between proclitics and
nonclitics, certain nonclitics are disposed to occasional clitic-like behavior. I propose
to capture this fact by distinguishing between inherent clisis vs. derived clisis, the
latter being sensitive to certain semantic, pragmatic, and prosodic conditions. This
approach allows us to address the striking similarities in certain behaviors between
clitics and nonclitics without ignoring their equally important differences.
