The prefix "psycho-" often refers to mental or psychological states, and there are several synonyms that can be used in its place for different contexts. For example, the prefix "socio-" emphasizes the social context of mental states. Other synonyms include "mentally unstable," "psychotic," "neurotic," "schizophrenic," and "deranged." In a medical context, terms such as "psychopathology," "psychosomatic," and "psychiatry" also relate to mental health. Words such as "crazy," "insane," and "mad" are less technical synonyms of "psycho-" and can be considered hurtful and stigmatizing to those living with mental health issues.
