Phono Online is designed to operate models of regular
historical sound change in natural languages. At present it has
access to a model for Pig Latin (children's "secret" language) and a model for Spanish.
Choose a model by clicking its button.
Type
an etymon (ancestor word) in the box and click "Derive".
Phono Online applies the sound-change rules of the model in
chronological order. Each time a rule effects a change, the
resulting form is displayed, alongside the name of the effective rule.
