Why “corroboration” is a great word
CORROBORATION — [Noun] The act of confirming or strengthening a statement, theory, or finding with additional evidence or authority. From Middle English corroboracioun, borrowed from Late Latin corrōborātiō (“strengthening”), from Latin corrōborāre (“to strengthen”), from com- (“together”) + rōborāre (“to make strong”), from rōbur (“strength, oak”). Unlike verification, which seeks to establish foundational truth through testing, or affirmation, which implies a subjective declaration of agreement, corroboration is the architectural buttress added to an existing structure. It is the second witness stepping into the courtroom, the matching fingerprint lifted from the glass, the archival document discovered in a forgotten chest—the slow, grain-by-grain accumulation that turns a solitary assertion into bedrock, a testament to our shared conviction that a story must be told more than once to be believed.

noun
- The act of corroborating, strengthening, or confirming; addition of strength; confirmation.“Fallacious enough doctrine when wielded against one's prejudices, but in corroboration of cherished suspicions not without likelihood.”
- That which corroborates.“Urban Dictionary records at least 66 of the terms found by the present research, but as this dictionary liberally accepts words, definitions, and sample sentences based solely on the say-so of contributors, in the absence of corroboration from other sources the authenticity of some entries must remain dubious.”
