“庶出”常见的英文表达是 “born of a concubine” 或 “of secondary wife/concubine's lineage” ，用于描述在封建宗法制度下，由妾所生的子女身份情况。
例如：
He was born of a concubine, so he had a lower status in the family compared to his elder brothers from the primary wife.（他是庶出，与正妻所生的兄长们相比，他在家族中的地位较低 。）
In ancient times, those of secondary wife/concubine's lineage often faced discrimination.（在古代，庶出的人常常面临歧视 。 ）
