It has been postulated that these objects are represented in the mind via feature geometry.
Optimality Theory proposes that a series of ranked constraints determine which of these objects is chosen in a given environment. In a phenomenon known as neutralization, distinctive features which contrast these objects may be eliminated. It has been postulated that these objects are represented in the mind via feature geometry. One way to determine whether two of these objects are in contrastive distribution is by looking at a minimal pair. Variants of these objects which occur in a predictable environment are called allophones. For 10 points, identify this linguistic unit, the smallest pairing of sound and contrastive meaning.
