Etymology: "Temerous" is an obsolete form of "temerarious," and the older word traces back to the Latin "temerarius," meaning accidental, casual, rash, or reckless. That Latin adjective was built on "temere," which meant "by chance, at random, rashly." The link between chance and recklessness is the heart of the story: the Romans treated acting without thought as acting by luck, so a rash person was one who left things to fortune. English took the word directly from Latin as a learned borrowing, rather than passing it through everyday speech, which is why it always sounded bookish. The form "temerous" is simply a shorter variant that dropped the "-arious" ending, and it has long since fallen out of use, leaving "temerarious" as the more familiar version among the two.
