extemporaneously

The word's journey begins with the Latin phrase ex tempore, literally meaning "out of time" or "from the moment." This described speech or action taken directly from the immediate time, without the delay of preparation. The root tempus (time) is of Proto-Indo-European origin, related to concepts of stretching and duration. Over centuries, the phrase was absorbed into English and elaborated with the adjectival suffix -aneous (meaning "of the nature of") to form "extemporaneous," and finally the adverbial -ly was added. Thus, the literal logic of "coming from the immediate time" evolved into the modern abstract meaning of doing something spontaneously, without prior planning.
