Unforsaken is an uncommon word, which means that there are few synonyms to describe the same idea. However, some alternative words that one can use include forsaken, abandoned, and deserted. These words all indicate an absence of something or someone, whether it be in terms of companionship or shelter. For instance, when speaking of an unforsaken territory, one might use the word "untouched" instead, to convey the idea that the area has remained unspoiled and natural. In any case, it is important to choose the right synonym to accurately describe the sentiment behind the original word, whether that is one of comfort or despair.
