The article provides an analysis of various aspects of intensification in the English language (colloquial and newspaper), intensifying adverbs in particular. The processes of grammaticalisation and delexicalisation observed in the evolution of intensifying adverbs are described. The author also looks into the renewal and boundedness of intensifying adverbs, provides an overview of modern classifications of intensifying adverbs, and offers statistics on the frequency of occurrence of intensifying adverbs to illustrate their usage in spoken discourse and newspaper language. The findings assume that less intensification is used in written discourse whereas more intensification is employed in spoken discourse, which suggests that the decline in intensification is higher as the formality of the register increases, and vice versa.
