Examination of a small segment of French morphology involving the role of the final consonant illustrates the applicability of the natural morphology approach to linguistic analysis. Representative examples of modern French adjectival, verbal, and nominal word forms are subjected to analysis in terms of iconic, non-iconic, and counter-iconic structure. The analysis also includes historical perspectives on the feminine, subjunctive, plural suffix, and prefix from late Latin and Old French. Extensive naturalness is found in this restricted corpus. The study concludes that the principal contribution of the natural approach is the maximization of the importance of iconicity of linguistic form, an aspect recognized but minimized in recent linguistic study, and that natural morphology appears to be a promising framework for both synchronic and diachronic morphological investigation in such areas as suppletion, verb stem allomorphy, and the rise of prefixation in nouns and verbs.
