In a manner that can be conjectured; based on or involving conjecture rather than certainty.
From conjecturable plus -ly adverb suffix. The -ly ending comes from Old English -lice, originally meaning 'in the manner of' or 'in the form of.'
When you use 'conjecturably,' you're honestly admitting your claim is educated guessing rather than fact—a rare moment of intellectual humility in how we speak!
