Spelman, voc.

Dirationare.

To disprove or refute the assertion of an adverse party. Spelman makes this to be the proper meaning, relying in particular upon the etymology of disrationare, (from dis, contrary, and ratiocinari, to reason.) See more under Disrationare, To put out of place or order; to displace or disarrange; to turn one out of his order; to degrade. Some of the old books give the word this sense, deriving it either from the Fr. disarrayer, to confound, or derayer, desranger, to derange or displace. Tennes de la ley.

Cowell. Co. Litt. 136.

This derivation, however, is not approved by Spelman.
