Word of the Day: Fugitive
The Latin phrase tempus fugit is thus translated 'time flies' by most people; that is, it eludes us, it escapes us by passing by too quickly for us to seize it. What I like about 'fugitive' is that it is not supposed to connote the sense of 'hiding from something' but that of 'escaping by being fast and elusive'.
That's why we learn about 'subterfuge', which means 'escaping by going underground' (fromsub- meaning 'below' and terr- meaning 'earth, ground') and 'centrifuge', which is about 'escaping (from) the centre'.
The meaning of such words, sadly, seems elusive. The fugitive sense of fugitive is what has drawn me to hunt down its etymology for my dear readers.
