Wintered is a term that is used to describe the season of winter or activities related to this period. This word can be substituted with several synonyms such as hibernated, endured, survived, or passed through. Hibernated is used when one has slept or stayed dormant for an extended period, just like bears and some other animals do during winter. Endured means to bear, tolerate, or go through a challenging situation. Survived also means to endure a hard or dangerous winter. Lastly, passed through is used when one has gone through a winter or period without incident or negative consequences. All these synonyms imply the idea of being through the winter season.
