易错句子The technician replaced two secondarys in the transformer.
正确表达The technician replaced two secondaries in the transformer.
secondary 是以「辅音字母 + y」结尾的可数名词,变复数时要先把 y 变成 i,再加 -es,所以复数形式是 secondaries,不能直接加 -s 写成 secondarys。这里 secondary 作名词,指变压器里的「次级线圈」。

易错句子In nickel defense, the secondaries is responsible for covering the receivers.
正确表达In nickel defense, the secondaries are responsible for covering the receivers.
secondaries 是可数名词的复数形式(美式足球中指列队于锋线后方的防守球员),复数主语必须搭配复数谓语 are;用单数 is 是把复数名词当成了单数,属于主谓一致错误。
grammar · medium
易错句子This transformer contains only one secondaries.
正确表达This transformer contains only one secondary.
one 表示「一个」这一单数数量,后面只能接单数名词 secondary;secondaries 本身已是复数形式,不能与 one 连用,需把数量词后的名词改回单数。
反义关系仅适用于 secondary 作名词的“次级飞羽”(附着于鸟类尺骨的飞羽)和“次级线圈”(变压器等中由初级磁力驱动的线圈)这两个义项;primary 作名词分别对应“初级飞羽”和“初级线圈”。在其他名词义项(如防守后卫、雷达二次回波)中不存在直接反义词。
在变压器语境中,primary 指接电源的初级线圈,secondary 指感应产生电流的次级线圈;二者是成对部件,不能互换。
