"Away" in the lines "Nothing you could do / That could turn me away" and "I won't move away" is sung with a melisma (Bb C Bb and Bb C Bb G, respectively), giving something of a sense of movement, although both are sort of negated.
The three syllables of "ev'ry word" in the line "Hanging on ev'ry word" are sung to all different pitches (F E D), lending a sense of number.
"All" in the lines "That's what you said / And I believed it all" is also sung with a melisma (C Bb G), here giving a sense of entirety, especially since these notes are all different pitches, too.
Finally, "go" in the line "I won't let you go" is sung with the same melisma (C Bb G), lending a sense of movement, although it seems to be used more metaphorically.
