Reciprocals routinely go unexpressed, thus diverging significantly from Spanish, where reciprocals use reflexive pronouns, e.g. se besaron 'they kissed each other', se mataron 'they killed each other'. Palenquero never uses reflexive or reciprocal Spanish se. Reflexives may also be unexpressed, or they may be expressed by the postverbal pronoun + memo construction.
