Alcophobin is a word that is not commonly used, but it is often seen in scientific literature. The word is spelled /æl-kəʊ-fəʊbɪn/ in IPA phonetic transcription. The first syllable, "al-" is derived from the prefix "alcohol-," meaning "relating to alcohol." The second syllable "-co-" is a shortened form of the word "cognitive." Finally, the suffix "-phobin" is taken from the Greek word "phobos" meaning "fear of." Therefore, the word "alcophobin" means "the fear or aversion to cognitive effects of alcohol."
