The act of assigning significance or meaning to something; secondary or additional significance.
From Latin 'ad-' (to/toward) + 'significare' (to make known) + '-tion.' The word means assigning or adding significance beyond the original meaning.
This word is basically 'assigning extra meaning'—like how historians add layers of significance to old documents—but the 'ad-' prefix and complex structure made it too cumbersome for modern English.
