At times, the phrase "sometime or other" may not fit well in certain sentences or situations. However, there are several alternatives that convey the same meaning. For instance, one could use the term "eventually" to indicate that something will happen someday, but without specifying a particular time. Another option is "at some point," which implies that the event may happen earlier or later, but it will occur eventually. Additionally, the phrase "one day" could be used, representing that there is no certainty about when something will happen, but it will happen one day. Other synonyms for "sometime or other" may include "in due course," "sooner or later," and "at a future period".
