El Nino, Spanish for the little boy is this irregular weather pattern that originates in the Pacific Ocean.

厄尔尼诺，西班牙语中的“小男孩”，是源自太平洋的这种不规则的天气模式。

Normally, words would tend toward the regular pattern of  adding " -s" or " -es" to make them plural — like how " agendum" became " agendas" and " hippopotami"   became " hippopotamuses" — but a few words tended toward the irregular pattern of zero plurals  instead.

正常情况下，单词会倾向于添加“-s”或“-es”来使其成为复数的常规模式 - 例如“agendum”变成“agendas”，“hippopotami”变成“hippopotamuses” - 但少数单词却倾向于不规则的零复数模式。
