Conjecturing is a broad term that encompasses a variety of activities, including FORECASTING (11 letters), ANTICIPATING (12 letters), DIVINING (8 letters), estimating (10 letters), GUESSING (8 letters), and declaring (9 letters). FORECASTING involves predicting future events or trends based on current data. ANTICIPATING is similar to FORECASTING, but it involves preparing for the future in advance. DIVINING is the practice of seeking knowledge through supernatural means. Estimating is the process of making an educated guess about the size, amount, or value of something. GUESSING is making an educated guess without any prior knowledge. Finally, declaring is making a statement or announcement.
