Definition
The set of features referred to as subsidiary place distinctions are those which can distinguish between two sounds sharing the same manner or place feature (for example, two fricatives may need to be even further defined in order to distinguish the two sounds). Subsidiary place distinctions include [+/- strident], [+/- anterior], and [+/-distributed].
A discussion of each subsidiary place distinction can be found by clicking the respective feature.
