where does the word achilles heel come from
Achilles' heel In Greek mythology, when Achilles was a baby, it was foretold that he would die young. To prevent his death, his mother Thetis took Achilles to the River Styx, which was supposed to offer powers of invulnerability, and dipped his body into the water; however, as Thetis held Achilles by the heel, his heel was not washed over by the water of the magical river. Achilles grew up to be a man of war who survived many great battles. One day, a poisonous arrow shot at him was lodged in his heel, killing him shortly afterwards.
Stepfamily The earliest recorded use of the prefix step-, in the form steop-, is from an 8th-century glossary of Latin-Old English words meaning "orphan". Steopsunu is given for the Latin word filiaster and steopmoder for nouerca. Similar words recorded later in Old English include stepbairn, stepchild and stepfather. The words are used to denote a connection resulting from the remarriage of a widowed parent and are related to the word ástíeped meaning bereaved, with stepbairn and stepchild occasionally used simply as synonyms for orphan. Words such as stepbrother, stepniece and stepparent appeared much later and do not have any particular connotation of bereavement. Corresponding words in other Germanic languages include: Old High German stiuf- and Old Norse stjúp-.[6]
