When referring to the northernmost point of something, there are several synonyms that can be used instead of "north-most". The term "northernmost" is the most commonly used term, followed by "northerly", which refers to anything in a northerly direction. Another possible synonym is "northern apex", which can describe a point or peak that is located at the topmost part of a northern area. Additionally, words such as "farthest north" or "most northerly" may also be used to describe the same concept. Regardless of the synonym used, they all refer to the point or area that is most northern in a specific region or location.
