paragraph;
parallel;
paralysis), "beyond, past, by'' (paradox;
paragogue);
by extension from these senses, this prefix came to designate objects or activities auxiliary to or derivative of that denoted by the base word (parody;
paronomasia), and hence abnormal or defective (paranoia), a sense now common in modern scientific coinages (parageusia;
paralexia). As an English prefix, para- ¹ may have any of these senses;
it is also productive in the naming of occupational roles considered ancillary or subsidiary to roles requiring more training, or of a higher status, on such models as paramedical and paraprofessional: paralegal;
paralibrarian;
parapolice.
