Imagine the first man discovering language, and the poem becomes a small creation story told in a few quick strokes. Adam's first word is "Good," and it seems tied to the senses: touching, eating, tasting the newly made world. Speech starts as pleasure, something felt in the body before it becomes an idea.
The middle stanza is stranger and more intense. A kiss "converts" the speaker, and his lips burn, as if words are heat that reaches "every creature within hearing." Naming becomes both gift and power. The final image compares speech to light that is magnified until it becomes "a whole hard day," which suggests that language illuminates but also brings effort and weight. The mood is wonder with a slight edge of strain. The poem feels fresh and excited at the start, then hints that speaking, like daylight, can be bright and demanding at once. The speaker seems amazed by words and a little burned by them.
