if i were pressed to give any example of a feature of this style , not only as an observable feature but as a source of pleasure to myself , i should mention the fondness for nasal consonants , especially the much-favoured n , and the frequency with which word-patterns are made with the soft and less sonorous w and the voiced spirants f and dd contrasted with the nasals : nant , meddiant , afon , llawenydd , cenfigen , gwanwyn , gwenyn , crafanc , to set down a few at random .
