What does credo mean?
A credo is a concise statement of the beliefs or guiding principles that shape a person's conduct or an organization's purpose. Borrowed directly from Latin, where credo means "I believe," the word entered English in the early seventeenth century and has since come to denote anything from a personal motto to a company's mission statement. Unlike a casual opinion, a credo suggests considered, deliberate conviction — something formulated, written down, and lived by. Speakers often use it to lend weight and sincerity to a declaration of values, as in describing a politician's credo or an artist's creative credo. The term also appears in religious contexts, most notably as the name of the Creed recited during the Mass. With its dignified tone and rich heritage linking it to words like credible, credit, and credential, credo remains a precise and evocative choice for expressing deeply held principle.
nounA set of beliefs or principles that guides someone's actions; a statement of personal or shared conviction.
- A formal or personal statement of the beliefs or principles by which someone lives.

"The company's founding credo emphasized honesty over profit."

The anglicized plural "credos" is standard. The Latinate plural "creda" exists but is rare and generally avoided in modern usage.
"The anthology gathered the artistic credos of twentieth-century painters."
Every 'I believe' you've ever uttered is, etymologically speaking, a tiny credo — the word comes straight from Latin's first-person 'credo,' meaning exactly that.

Etymology of credo
Credo comes directly from Latin credo, meaning "I believe," the first-person singular of credere ("to believe" or "to trust"). English adopted the word in the early seventeenth century, initially with reference to religious creeds before broadening to any statement of guiding principles. It shares this Latin root with cognates such as credible, credit, credential, and incredulous, all built on the idea of trust or belief.
How credo is actually used
"Credo" carries a slightly formal, even literary register compared with everyday words like "belief." It often implies a concise, deliberately articulated set of principles rather than a vague outlook. The plural "credos" is standard in English, though "creda" occasionally appears as a Latinate variant. It is also capitalized (Credo) when referring to the portion of the Christian Mass that begins with the Latin words "Credo in unum Deum" ("I believe in one God").
