Gerunds are special forms of verbs that have nominal usages. In English, gerunds end in –ing. For example, in the sentence Swimming is fun, swimming is a gerund. Some authors also use this term for "present participles, found in progressive constructions as in He was swimming.
Gaelic doesn't have Gerunds. Instead the nominal form of verbs is called the verbal noun. Verbal nouns are used in a variety of contexts including progressives, perfects, infinitives, non-finite clauses and purpose clauses as well as nouns in argument positions
