Relating to or involving concordance or agreement; characterized by harmony or consistency.
From concordant with the suffix -ial (of or relating to), creating a more formal or technical adjective variant for describing things marked by agreement.
This ultra-formal adjective might appear in legal treaties or philosophical treatises, but it's so rare that most dictionaries don't even list it—it's the kind of word that makes readers pause and wonder if it's a typo.
