IPA: /ˈpɜːrfəreɪtɪd/
KK: /ˈpɜrfəˌreɪtɪd/
Describing something that has holes or openings, often arranged in a pattern, such as in paper or metal.
The perforated paper made it easy to tear off the sheets.
Perforated → It is formed from "per-" (meaning through) and "forare" (meaning to bore or pierce). The word describes something that has been pierced or bored through, creating holes throughout.
Think of something being 'bored through' ('forare') to create holes 'through' ('per-') — that's what perforated means.
