The term “palindrome” comes from the Greek words “palin,” meaning “again” or “back,” and “dromos,” meaning “running” or “course.” It refers to a word, phrase, number, or other sequence of characters that reads the same forward and backward.

1. Proto-Indo-European (PIE)

The PIE root “*kwel-” means “to turn” or “to move around.”

2. Greek

From the PIE root, the Greek word “dromos” developed, meaning “running” or “course.” The prefix “palin-” means “again” or “back.” Combined, they form “palindromos,” meaning “running back again.”

3. Modern English (from the 17th century CE to present)

The term “palindrome” was adopted into Modern English from Greek, retaining the meaning of “a word, phrase, or sequence that reads the same backward as forward.”
