This page allows the user to interact with an implementation of the model of reduplication developed in our manuscript Reduplication as Projection [2020 update: the most recent version of the paper is available here]. The model is closely derived from Halle's 2008 approach:
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.
(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.
