What does truly mean?
Truly is an adverb meaning genuinely, really, or completely, with the exact emphasis depending on context. Before a description, it can assert that a quality is authentic or unusually pronounced: “a truly excellent performance.” Before a verb or in a statement about belief, it often means sincerely or in reality: “I truly believe we can succeed.” In letters and formal closings, such as “yours truly,” it conveys faithfulness and goodwill. The word is used in everyday conversation as well as in formal writing, although emphatic repetition can sound theatrical. Its history is closely connected with the idea of being true or faithful. Today, it remains useful because it can distinguish genuine reality from mere appearance while also adding emphasis without requiring a more formal alternative.
In a genuine, real, complete, or emphatic manner; really.

Archaic: genuine, true, or faithful.

This older adjective sense is rare in contemporary standard English; most modern uses of similar wording are adverbial.
Truly began as a word for faithfulness: the idea of being true to someone or something still gives the modern adverb its sense of genuine reality.

Where does truly come from?
Truly developed in Middle English from forms associated with the Old English word meaning “faithful” or “true,” combined with the adverbial suffix -ly. Its historical meaning therefore centered on being true to a person, promise, or principle before it broadened to mean genuinely or completely. The English words true, truth, and trust share the same ancient Germanic and Indo-European heritage of faithfulness, trust, and fidelity. In modern usage, the older sense of true loyalty survives especially in formal expressions such as “yours truly.”
How truly is actually used
In modern standard English, truly is an adverb and is common in both formal and informal contexts. It can emphasize sincerity, authenticity, or degree, but repeated use may sound emphatic or rhetorical. Its older adjective sense is now archaic.
