Marked or accompanied by loud, ringing metallic sounds; resounding with clangs.
From 'clang' (sharp metallic sound, possibly from Latin 'clangor') plus suffix '-our' (British spelling variant), then '-ed' (past participle/adjectival form). The term describes things that have undergone or are characterized by clanging.
Medieval and industrial-age writers loved 'clangoured' to describe battle scenes and factory floors—it's a word born from the noise-pollution experience of humanity learning to work metal and wage mechanized war.
