the two words that make o'clock r o and clock. three words actually..... of the clock.
O'clock is a contraction of 'of the clock' so it is a short way to say the time is three of the clock or whatever time being refered to.
Have one stick be twice the length of the other. With the double length stick, you would split the clock face in two, and with the regular length stick you could split one of those divisions into another two, effectively creating three divisions. Another way to look at it is to place the double length stick from 12 o clock to 6 o clock, and the regular stick from 3 o clock to the middle of the clock.
o'clock means of the clock.
