Quick comparison

The Origin of Lily or Lilly
The word lily has a long linguistic history. It comes from the Latin word “lilium”, which described the elegant flowering plant known for its beauty and fragrance.
Over time, the word traveled through different languages:
| Language | Word |
| Latin | lilium |
| Old English | lilie |
| Middle English | lily |
| Modern English | lily |
The spelling gradually stabilized as lily in modern English.
So where did “lilly” come from?
The double-“l” spelling mostly developed as a family name. In some regions, surnames evolved from personal names or occupations, and spelling variations appeared because spelling rules were not standardized centuries ago.
As a result, Lilly became a surname and later appeared in brand names and organizations.
But the plant name remained “lily.”
British English vs American English Spelling
Many English spelling differences exist between British and American English.
Examples include:
| American English | British English |
| Color | Colour |
| Center | Centre |
| Favorite | Favourite |
Because of these differences, many people assume lily vs lilly is another regional variation.
However, that assumption is incorrect.
Both British English and American English use the same spelling: lily.

| Usage | American English | British English |
| Flower name | Lily | Lily |
| Common first name | Lily | Lily |
