The word "imperilled" is derived from the word "peril", which originates from the Old French word "peril" or "péril", and Latin "periculum", meaning "danger" or "dangerous". It entered the English language around the 14th century. The prefix "im-" added to "peril" forms "imperil", which means to put someone or something in danger or jeopardy.
