I know that there are many words from other languages that have become part everyday use in English. But I have not heard of some of these words--juger, for example. Also, I cannot explain the first N in BRETHREN.

Plurals … one the main banes of incorrect usage of the English Language. We thought we’d bring you some of the more odd or obscure plurals of words as an added bonus on today’s FlowGo “Word Flex”. Singular on the left, plural on the right… you don’t just add “s” to these words:
