ABSTRACT
Adverbs are normally used to qualify a verb, adjective, or the entire sentence. Many are derived from descriptive adjectives; others, especially those referring to time and place, are not.
Adverbs may be formed from adjectives by adding the particle go, which prefixes h-to a vowel but does not alter a consonant:
Tá Bairbre cúramach. Bairbre is careful. Rinne sí an obair go cúramach. She did the work carefully.
