The Beowulf manuscript, copied around the year 1000, preserves a poem whose composition history is older and more complex than the surviving codex. The Lindisfarne Gospels gloss, added around the tenth century, places an Old English translation beside a Latin Gospel text. A gloss is evidence for a reading practice and vocabulary, not a full recording of everyday speech.
The Dictionary of Old English, manuscript catalogues, charters, place names, and comparative corpora allow researchers to test forms across witnesses. Spelling, scribal habit, manuscript date, dialect, and editorial normalization must remain visible when a modern reader meets a clean printed form.
