⊢ overview

(with Charles Reiss)

This page allows the user to interact with an implementation of the model of reduplication developed in our manuscript Reduplication as Projection. The model is closely derived from Halle's 2008 approach:

  • Reduplicative morphology consists of the insertion of various junctures at phonologically defined anchor points within a morphological domain, such as a stem
  • The phonology interprets the brackets by projecting material within their scope to create a hierarchically structured representation whose linearization is simply read off from the terminal nodes in the resulting tree from left to right.

In the paper, the structures are shown to play a role in the application of structure-dependent phonological rules, allowing us to generate so-called "backcopying" effects derivationally.

⊢ a brief explanation of the junctures

(We recommend that you read the second section of the paper before proceeding.)

The top-level reduplication domain must be defined by surrounding phonological material with square brackets. For example: given a[bcd]e, the reduplication domain is bcd. The edges of a reduplication domain delimit substring projection and nesting.

Within the reduplication domain, the following junctures can be used:

Juncture Description
} Define a nested reduplication domain containing material to the left of the juncture in the left branch.
{ Define a nested reduplication domain containing material to the right of the juncture in the right branch.
< Only interpretable in the left branch: project material to the right of the juncture.
> Only interpretable in the right branch: project material to the left of the juncture.

N.B. Our definitions of < and > are essentially complements of those presented in Halle 2008 for reasons explained in the paper.
