What does jestful mean?
Jestful is an uncommon adjective with two related but contrasting associations. In its older and best-known literary expression, “in jestful earnest,” it means serious, sincere, and without joking. Elsewhere, especially in descriptions of a person’s mood or behaviour, it can mean full of jest, playful, or given to humour. The second sense is the more transparent one because it directly combines the word jest with the suffix -ful, meaning “full of.” The serious sense is historical and may initially seem contradictory, which gives the word its memorable quality. Although no longer common in everyday English, jestful survives in formal, literary, and deliberately traditional contexts. It is also occasionally confused with jocular, which similarly means humorous or playful but does not ordinarily carry the older sense of earnestness. A writer might choose jestful when the context evokes an earlier period, emphasizes a mixture of humour and gravity, or deliberately uses the established phrase “in jestful earnest.”

In the phrase “in jestful earnest,” the word means completely serious—a humorous reversal in which “jestful” points to truthfulness rather than joking.

Where does jestful come from?
Jestful was formed in English by combining jest with the suffix -ful. Jest comes through Old French geste from Latin gesta, “deeds” or “exploits,” and originally referred to a story, tale, or adventure before developing its modern meaning of something said for amusement. The older sense of jestful meaning earnest or serious arose in contrast to language or conduct meant only in jest; its best-known surviving expression is “in jestful earnest.” The modern playful sense follows more directly from the literal meaning “full of jest.”
How jestful is actually used
Now rare and chiefly literary. The expression “in jestful earnest” preserves the older, serious sense; in other contexts, “jestful” more directly means playful or full of humour.
