Concludingly is a word used to signify something that is final or coming to an end. However, there are several other synonymous words that can be used to convey the same meaning. These words include "finally," "ultimately," "eventually," "lastly," "in conclusion," "to sum up," "to conclude," "in the end," and "at last." Each of these words serves to emphasize the end of a particular event, thought, or situation. They can be used interchangeably to express the same idea. So, instead of always using concludingly, one may consider mixing up these synonyms, or finding other ways to express a similar idea.
