Defining distributions: consonant allophones
Phonemes revisited
The two major criteria for establishing phonemic contrast are predictability of occurrence, and invariance of meaning. That is to say, if we are dealing with two allophones of the same phoneme, the two must occur in non-overlapping sets of environments. Furthermore, there cannot be any minimal pairs, where substituting one of our focus sounds for the other in exactly the same context creates a difference in meaning. These two criteria establish conclusively that English [ɹ] and [l] belong to distinct phonemes: there are many minimal pairs, like rip and lip, rot and lot, marrow and mallow, so clearly the two phones occur in the same contexts; and substituting one for the other does create a meaning difference. On the other hand, clear, alveolar [l] and dark, velar
occur in predictably different environments: in Standard Southern British English, the clear, more front one appears word-initially or between vowels, as in lip, lot, mallow, and the dark, more back one word-finally or before a consonant, as in pill, tall, halt. Since there are no minimal pairs, and substituting one variant for the other will not make a meaning difference, [l] and
are necessarily allophones of a single phoneme, /l/.
Equipped with the articulatory descriptions from the last chapter, we can now progress to a more detailed account of the distribution of allophones. In doing so, we will also discover that certain phonemes form groups, in that they have similar allophones in similar environments. We must try to identify what members of such groups have in common, and what makes certain phonemes work together.
