Acidismus is spelled: /əˈsɪdɪzməs/. This word is not commonly used and there are no context clues available to provide its meaning. However, by looking at the IPA phonetic transcription, we can decipher its pronunciation. The /ə/ sound at the beginning is an unstressed schwa sound. Following that is the stressed syllable containing the /sɪd/ sound which is pronounced as "sid". The suffix /ɪzməs/ denotes a doctrine or theory. Therefore, we can infer that Acidismus refers to a theory related to acid or acidic substances.
Poisoning by acids introduced from without, as contradistinguished from acidosis, or poisoning by acids formed in metabolism.
