• Old French: Reel helped shape the English word real.
• Old English (450 to 1100): The prefix un- has Old English roots, but the full word unrealistic did not exist in this period.
• Middle English (1100 to 1500): Real entered English through French, but the full word unrealistic was not yet in use.
• Modern English (1500 to present): Realistic developed from real and the suffix -istic. Adding un- formed unrealistic, meaning not realistic.
