Pronunciation ˌpriːəˈkluːʒn

A sound change that introduces a homorganic voiced plosive before a nasal stop. This occurred in Cornish for example, where it is confined to the coda of stressed syllables – for example, pen (“head”) penpedn pedn. A similar phenomenon occurs in Manx. For instance, lhong (“ship”) loŋloɡŋ.
