More about horripilation
When delving into the history of horripilation, things become hairy rather quickly. The horri- part comes from a Latin verb meaning 鈥渢o bristle,鈥� and this verb is also the source of words such as horrendous, horrify, and horror. Unlike terror, which literally has to do with being frightened, the root of horror is all about hair standing on its end! In addition, the -pil- part of horripilation is a Latin stem meaning 鈥渉air.鈥� Horripilation was first recorded in English in the 1650s.

to undergo or be capable of undergoing a change in form or nature.
More about metamorphose
Metamorphose 鈥渢o undergo a change in form or nature鈥� is a back formation from the noun metamorphosis 鈥渁 complete change in form.鈥� As we learned from the recent 51吃瓜 of the Day defenestrate, a back formation is a word created from another by cutting off a suffix (or what seems to be a suffix) from the older word, such as the verb edit from the noun editor. The noun metamorphosis is a compound of the combining forms meta- 鈥渁fter, beyond鈥� and morph- 鈥渇orm, structure,鈥� which come from Ancient Greek 尘别迟谩 鈥渂etween, after鈥� and 尘辞谤辫丑岣� 鈥渟hape,鈥� respectively. Though linguists have tried to connect Ancient Greek 尘辞谤辫丑岣� with its Latin equivalent, forma 鈥渇orm, model,鈥� based on the words鈥� shared sounds, it remains unclear whether the resemblance is merely a coincidence. Metamorphose was first recorded in English in the 1570s.
how is metamorphose used?
A cellular-automata simulation involves a chessboardlike grid of squares, or cells, each of which is either empty or occupied by one of several possible components. At discrete intervals of time, each cell looks at itself and its neighbors and decides whether to metamorphose into a different component. In making this decision, the cell follows relatively simple rules, which are the same for all cells.

More about uraeus
Uraeus, 鈥渢he sacred asp on ancient Egyptian headdresses,鈥� comes from Late Greek 辞耻谤补卯辞蝉, of the same meaning. This 辞耻谤补卯辞蝉 appears identical to Ancient Greek 辞耻谤补卯辞蝉, 鈥渙f the tail,鈥� but the two likely do not share a deeper origin; while 辞耻谤补卯辞蝉, 鈥渙f the tail,鈥� comes from 辞耻谤谩, 鈥渢ail,鈥� and is the source of the English combining form uro- (not to be confused with 辞没谤辞苍, 鈥渦rine,鈥� the source of a different uro-), 辞耻谤补卯辞蝉, 鈥渦raeus,鈥� comes from Egyptian 测鈥檙迟, 鈥渞earing cobra,鈥� which is also transliterated variously as iaret or 箩隃迟. Though uraeuses is the standard plural, the alternative uraei appears in some texts. Uraeus was first recorded in English circa 1830.
