Relative proficiency in Gaelic varies by age in a Highland Scottish region where Gaelic is spoken by a decreasing number of bilinguals in a steadily aging population segment. Although there is a Gaelic proficiency continuum ranging from full fluency (and Gaelic dominance) to minimal generative skills (and English dominance), there are also deviations at both extremes of skill: Fully fluent speakers show self-conscious difficulty with one morphological and four syntactic structures, while minimally proficient speakers show less difficulty than might be expected in the use of conjunctions. An exceptionally keen though low-proficiency speaker can devise unusual means of compensation in using the language. Neither full fluency nor marked deficiency produces altogether predictable levels of structural conservatism or communicative success.
