IPA: /ˌtɛm.əˈrɛr.i.əs/
KK: /tɛmɪˈrɛriəs/
Showing a lack of caution or care; being recklessly bold or daring.
His temerarious decision to climb the mountain without proper gear surprised everyone.
Temerarious is derived from the Latin root "temerarius" (meaning rash or reckless), which comes from "temere" (meaning by chance or blindly). The word describes someone who acts recklessly or without careful consideration.
Think of someone acting 'blindly' ('temere') and 'recklessly' — that's why temerarious means acting without caution.
