The word "anatherapeusis" is a Greek word that means "another treatment". It is composed of several Greek roots: ana- (meaning "up" or "again"), therapeia (meaning "treatment"), and -sis (meaning "process" or "action"). The correct spelling of this word is [əˌnæθəˌɹæpjuːsɪs], with an initial schwa sound, followed by stress on the second syllable, and the final two syllables pronounced as "rap-yoo-sis". The pronunciation may be a challenge for some, but the meaning of the word is clear: "another treatment".
