IMMEDIATELY, at once — Mark's signature word and the engine of his Gospel. It appears about forty times in these sixteen short chapters (eleven in chapter 1 alone), far more than in all the rest of the New Testament combined, driving the narrative at a breathless run: Jesus calls, and 'IMMEDIATELY they left the nets'; he speaks, and 'IMMEDIATELY' the leprosy is gone. ⚠️ It is not filler. The relentless EUTHYS is Mark's theology in an adverb — a kingdom breaking in with no pause for deliberation, a Jesus always in motion, a story that never sits down. Most translations vary it ('at once,' 'quickly,' 'straightway') for English elegance; keeping it consistent lets the drumbeat land. Same word EUTHEIAS in 1:3, 'make his paths STRAIGHT' — the root sense is 'straight,' and time-wise, 'straightaway.' KJV 'straightway,' its old catch-all for the word. → first discussed at Mark 1:10
