If you use an old expression like "by a many", do you need to make it consistent and use old expressions throughout the poem, or is it ok to just use it in one verse or sentence?
“The spring is coming by a many signs.”
I was wondering if we can for example use an old archaic expression one time and then never use any archaic word or expression. I am pretty sure the answer is different depending on whether you're writing a poem or novel.
