engross
/ɛnˈɡɹəʊs/verb
To copy a document in large, clear, carefully formed lettering; to prepare its final official version.
Example sentence
- “The clerk engrossed the treaty on parchment for the official signing.”
The living use is 'engrossed in': absorbed so fully in a book or task that you notice nothing else. The clerical copying sense is legal history.
