praise: [13] Despite a certain similarity in form and meaning, praise has no connection with pray. It comes ultimately from Latin pretium ‘price’, which has also given English precious, price, prize, etc. From it was derived the late Latin verb pretiāre ‘value highly, praise’, which English acquired via Old French preisier.
