An archaic or obsolete abbreviation or short form, possibly relating to abstract or abstraction (extremely rare and non-standard).
This entry is highly questionable as a standard English word; it may represent an obsolete abbreviation or manuscript shorthand from medieval texts, but it does not appear in modern English dictionaries as a complete word.
If this appears in any historical text, it's likely a scribal abbreviation rather than a complete word—medieval monks used shorthand symbols and abbreviated forms constantly to save expensive parchment, creating mysteries for modern readers trying to decipher old manuscripts.
