Source and review context
This entry combines structured lexical data with WordToolSet review checks. Definitions, examples, synonyms, and usage notes may come from different source tables, so the page is designed to show evidence from more than one angle before you rely on "lucy" in a final draft.
If a word has several senses, prefer the sense that matches your sentence's grammar and surrounding context. A correct definition can still be the wrong choice when the sentence needs a different register, emphasis, or level of specificity.
Before you rely on this definition
Read the first definition as a starting point, then check the example, synonyms, and part of speech before treating "lucy" as the right word for your sentence.
If your draft is formal, technical, persuasive, or sensitive, compare "lucy" with a nearby alternative so the final choice matches both meaning and reader expectation.

Definition decision workflow
1. Identify the role
Check whether "lucy" is acting as name, noun, slang in your sentence. A definition is only useful when the grammar matches the way the word is being used.
2. Test the nearest option
Compare it with "first name" and other nearby choices to see whether the sentence needs a softer, stronger, or more familiar word.
3. Confirm with context
Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.
Review note: Definition pages are checked for source coverage, sentence evidence, synonym support, and editorial insight before they are treated as approval-ready pages. If the evidence is too thin, the page remains available to users but is kept out of the approval-facing indexed inventory.
Final meaning check
Before publishing a sentence with "lucy", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.
When the definition, synonym evidence, and example context point in the same direction, the word is usually a safer choice. When they conflict, revise the sentence or choose a clearer alternative.

Etymology
Etymology 1
From Middle English Lucy, from Old French Lucie (notably after the Christian martyr Lucia of Syracuse), from Latin Lucia (feminine of Lucius, a Roman praenomen), from lux (“light”). The name of the Australopithecus skeleton came from the Beatles song “Lucy in the Sky with Diamonds”, which was being played repeatedly at the dig site camp at the time of the discovery. The slang term for LSD also derives from the song name, which many believe is essentially a reference to the drug.
Etymology 2
From Latin lūcius.
