Bound Morphemes are used to express the Past Tense in English.
2. Present/Past: There is no doubt that folks in our Society are particularly concerned with time. We live by the clock.
In my office which is 8Åx8Å, I have three clocks on the wall, and if that werenÅt enough, I wear a watch and my computer keeps the time at the top of the screen.
So how many bound morphemes do we devote to expressing time--that is, how many tenses do we have in English? Take a guess...2, 4, 6, 8 or more?
I you answered 8 or more, you are in for a surprise. The answer is 2! They are the Present and Past Tenses.
We do have other mechanisms for expressing nuances of time, but they do not involve bound morphemes. We will discuss those later.
So today I jump. Yesterday I jumped. The bound morpheme expressing past tense is pronounced /t/ (although it is spelled "ed.")
