In situations where we can't completely rely on something or someone, we often use the phrase "not reliably." However, there are several synonyms for this phrase. One is "erratically," which means something is unpredictable and unreliable in its performance or behavior. Another is "intermittently," which suggests that something occurs infrequently and in an irregular manner. "Inconsistently" conveys a similar sense of unreliability, as does "unpredictably," which implies that something is impossible to forecast or anticipate. These words are useful in situations where we need to describe behavior or outcomes that are uncertain and lack a consistent pattern.
