An archaic or obsolete spelling of 'general,' formerly used in older English texts.
From Old French general, from Latin generalis. This spelling (with double-l) appears in Middle and Early Modern English texts before standardization occurred.
Finding 'generall' in Shakespeare or the King James Bible shows that spelling was once a free-for-all—people spelled however made sense to them, and it took centuries of printing presses and dictionaries to enforce the single 'general' we use today!
