This paper proposes to reinterpret cyclic effects not as input-output

relations between separate levels (McCarthy & Prince 1993, Kenstowicz

1994) but rather--building on the proposals of Kraska (1995)--as

similarity constraints between and among morphologically related words

(cf. similar proposals independently developed by Benua 1995, Burzio

1995, McCarthy 1995, Steriade 1994, among others). In particular, a

constraint of Base-Identity is proposed that evaluates candidates for

a complex word [X+Y] on the basis of their similarity to the immediate

constituents [X] and [Y] to the extent that the latter occur as

independent outputs. In the first section we review previous

approaches to cyclicity in the OT framework and propose an alternative

in terms of the Base-Identity requirement between independent output

forms. In the second section we discuss cases (Italian /s/-voicing,

Korean cluster simplification and default accent) in which the

availability of a constituent of the derivative as an independent word

plays a crucial role. We then examine examples where the similarity

effect is sensitive to the gross prosodic structure of the base

(Palestinian Arabic, Dutch). The final section reviews similarity

effects that do not fall under the rubric of identity to the base as a

separate word. For these we posit a constraint of Uniform Exponence

(Flemming 1995) that evaluates sets of morphologically related words

for segmental and prosodic similarity. Various instances of paradigm

leveling (Spanish, Swiss German, Latin, Polish) are analyzed in these

terms. The paper closes with an overview of the range of observed

similarity effects.
