59. A consonant preceded by a prefix was treated as an initial
consonant as long as the character of this preceding syllable was
recognized: _de-cadĕre_ ＞ decazẹr, _de-pĭngĕre_ ＞ depẹnher,
_præ-parāre_ ＞ preparar, _re-cordāre_ ＞ recordar, _re-patriāre_ ＞
repairar, _re-pausāre_ ＞ repausar, _se-dūcĕre_ ＞ sedüire. If, however,
the initial syllable ceased to be recognized as a prefix, the following
consonant was treated as a medial consonant: _præpŏsĭtum_ ＞ prebǫst,
_retŏrta_ ＞ redǫrta; so, perhaps, _profŭndum_ ＞ preọn. The rare
rebọnre (beside repọnre) ＜ _re-pōnĕre_ has the special sense ‘to
bury’.
