The term 'up until now' can be expressed in several ways, each with a slightly different meaning. The word 'YET' (3 letters) implies that something has not happened, but may still happen in the future. 'HITHERTO' (8 letters) means up to this point in time, and is often used to refer to something that has been done or experienced in the past. 'Sofar' (5 letters) is similar to 'HITHERTO', but implies that something has been done or experienced up to a certain point, but may change in the future. 'HERETOFORE' (10 letters) is a more formal way of saying 'up until now', and is often used to refer to something that has been done or experienced in the past. 'Asyet' (5 letters) is another way of saying 'up until now', but implies that something has not YET happened. Finally, 'todate' (6 letters) is a way of saying 'up until now' that implies that something has been done or experienced up to the present moment.
