([britannica.com](https://www.britannica.com/dictionary/series?utm_source=openai))  \n- You **don\u2019t** add \u201c-es\u201d or anything else (so *serieses* would be incorrect). ([lawprose.org](https://lawprose.org/garners-usage-tip-of-the-day-series/?utm_source=openai))  \n\nUsage examples:\n\n- Singular: \u201cThe TV *series* is popular.\u201d  \n- Plural: \u201cAll those *series* are popular.\u201d\n\nIf you need help figuring out whether to use singular or plural verbs with *series*, I can explain that too."
