What are the three categories of adverb?
Though adverbs as a grouping are less clearly defined than other word types such as verbs and nouns, it is possible to categorise words like ‘additionally’, ‘furthermore’ and ‘somewhat’ in three distinct ways. There are adjunctive, conjunctive and disjunctive adverbs, each of which has multiple subcategories:
1) Adjunctive adverbs add optional information about an event or state in relation to its circumstances, such as its place, time, condition or manner (‘I failed the exam this morning.’).
