Are prayers cliches?

In my  previous post I said it was not a good idea to use cliches as they are second hand.But prayers or songs are words which have been used many times before.And will  go on being used until we blow ourselves up.And fairy tales and stories are also repeated down the generations.
Are these cliches?
With prayers I suppose for ones which are in the liturgy we need something we can all say together.Yet even such a prayer can become a meaningless habit.Similarly we will hear tomorrow hymns about Jesus and the Resurrection;hymns  in which we promise to be good,compassionate etc
Then we leave the church and return to our usual mode of life.So being too familiar we do not always hear the prayers or hymns.So in that sense thay have become cliched language which has been emptied of meaning by over-use.
Maybe that’s why Quakers are silent until a person gets a thought they want to share.It is spontaneous.
Some prayers and chants are meant to alter our consciousness.Repeating words is usual in meditation.But unless we want to do it it can be meaningless like saying the rosary may be.It was a trial to me as a child.

In the end we can only reduce the amount of second hand language we use anut d try to look at our loved ones afresh daily.We can’t  recreate the world every hour.But maybe we can become more aware of what we say.
