"Re-warns" is a term that is commonly used to describe the act of warning someone twice, after they have already received a previous warning. However, in English language, there are several synonyms that can be used in place of "re-warns," such as caution or advise. Other synonyms for warn are alert, notify, inform, forewarn, or apprise. Each of these words carries subtle differences in their meanings, but all serve as alternative options when discussing warning others multiple times. It is important to note that, regardless of the word chosen, effective communication and follow up remain key elements in ensuring that warnings are taken seriously and acted upon appropriately.
