I have noticed the word "lower" has to distinct pronunciations.
My question is whether such distinct pronunciations are related to distintic meanings of the word lower.
For example, when the word "lower" stands for the comparative of "low" is its pronunciation always the same (\ˈlō-ər\)?
And what about the noun "lower" is it true that the pronunciations of "lower" and "lour" match exactly the same?
