When threads break, it can be frustrating and time-consuming to repair them. Luckily, there are several synonyms for "broken threads" that can be used in different contexts. One option is "frayed threads," which implies that the threads have become unraveled at the tips. Another option is "split threads," which suggests that the fibers have been divided and may be less usable. "Torn threads" is another possibility, particularly if the breakage is more extreme. Overall, using a variety of synonyms can help to add variety and nuance to your language when discussing thread-related issues.
