I'm well aware that bulwark refers to something used as a fortification or a defense. However, I was wondering if the word bulwarker is an acceptable word to use in English.
I know it's possible to be a bulwark ("He built a bulwark upon the hill."), and I know you can bulwark something from something else ("I will do whatever I can to bulwark the attack."). However, I'm unsure if it is possible to be a bulwarker.
