Plural of deletion; acts or instances of removing or erasing something, or the things that have been removed.
From Latin deletio (from delere, 'to destroy'), adopted into English with the Latin suffix -tion/-sion to create nouns from verbs. The plural adds -s in regular English fashion.
In genetics, 'deletion' is a specific mutation where a segment of DNA vanishes—nature's own delete key—and scientists realized evolution happens just as much through removal as through addition.
