Pronunciability scores for 144 CVCs were obtained by means of actual latency data and compared with Underwood and Schulz's pronunciability ratings in terms of their respective correlations with meaningfulness (Noble's m'). It is concluded that, while both pronunciability measures have significant commonality with scaled meaningfulness, the correlation involving Underwood and Schulz's ratings and m' is spuriously high. Since studies of the effect of pronunciability in verbal learning have commonly employed ratings of the Underwood and Schulz variety, it is suggested that any conclusions about the effect of pronunciability on the acquisition of CVC trigrams should be considered highly tentative.
