Time and tide wait for no man.
Time. I’m trying to say that today’s word is time.
Time comes from the Old English tima, which meant, no fooling, limited space of time. It wasn’t until later that it meant a continuous amount of time, can you believe it? It comes from the Proto Germanic timon, time, and Proto Indo European di-mon-, a form of the word da, which is also the ancestor of tide.
