buttress (n.) any prop or support
buttress (v.) to support by a buttress; prop up
Words like combat, abstract, project, and convict change the syllable that's stressed based on whether you're using their noun or verb or adjective form. I thought the word buttress, which has both noun and verb forms, should also follow the rule like the others do, but I can't seem to find anything that differentiates its pronunciation based on its part of speech. Does anyone know if it follows this initial-stress-derived noun rule? I know it's not much of an established rule and buttress could be an outlier but I'm just not sure.
