1. In a recent article1 it was suggested that a statistical analysis of the relative frequency of consonant clusters would reveal an 'other-than-chance' distribution. Specifically, it was hypothesized 'that the average frequency of a consonant cluster is a function of the difference between the phonemes in the cluster: low frequencies are expected for clusters which are either extremely similar or extremely dissimilar; high frequencies are expected for clusters which are at neither extreme' (25). The results based on texts in Spanish and English seemed to substantiate the hypothesis: 'the distribution of the average frequencies of clusters [when frequency is plotted against similarity] tends in both languages to follow a normal curve' (29). The present study attempts to test the hypothesis further on the basis of Chontal, a Mayan language spoken in Tabasco, Mexico;2 and, in addition, on the basis of the Chontal data, re-examine some of the assumptions involved, and discuss some of the problems.
