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 betw
een proclitics and nonclitics, certain nonclitics are disposed to occasiona
l clitic-like behavior. I propose to capture this fact by distinguishing be
tween inherent clisis vs. derived clisis, the latter being sensitive to cer
tain semantic, pragmatic, and prosodic conditions. This approach allows us
to address the striking similarities in certain behaviors between clitics a
nd nonclitics without ignoring their equally important differences.
