Ludwig's WRAP-UP
In summary, "should they fail" is a grammatically correct and frequently used conditional clause that introduces a hypothetical scenario where an action doesn't succeed. As highlighted by Ludwig, its primary function is to set the stage for discussing the consequences or alternative actions that would follow such a failure. Predominantly found in news and media, as well as scientific contexts, it maintains a neutral to formal tone. When employing this phrase, ensure that the subsequent clause clearly outlines the repercussions of the failure to maintain clarity and impact. Remember that while alternatives like "if they don't succeed" exist, "should they fail" carries a more formal and emphatic tone, which may be better suited for certain writing contexts.
