Plural of gerund; verb forms ending in '-ing' that function as nouns in sentences (like 'swimming' in 'Swimming is fun').
From Latin gerundium (from gerere 'to carry, conduct'), which refers to a form expressing the action of a verb; the -s makes it plural.
Gerunds are why English can say things like 'I love running'—turning verbs into nouns was revolutionary because it let speakers treat actions as objects, unlocking entirely new ways to express thoughts.
