This study attempts to consider some aspects of adverb-adjective collocation in English. It explores the semantic properties of some adverbs and their collocating adjectives recorded in two collocation dictionaries, namely, Oxford Collocations Dictionary (OCD) and the LTP Dictionary of Selected Collocations (LTP). The central questions that have guided this analysis are: what exactly does an adverb do to an adjective in Adverb-Adjective Collocation? and what are the restrictions on the combinability of the two lexical items?
