Definition: The word "antonymic" means opposite or contrary in meaning. Definition: It refers to a word or phrase that has a positive (like "good") or negative (negative) meaning, as opposed to an antonym which has only one meaning. For example, in Greek, "perfect" can be either the perfect number 10, which is a number 98% accurate, or the perfect vowel, which is a vowel that sounds like a consonant and also starts with a consonant. So, if we look at "happy", it's both a positive (happiness) and a negative (sadness).
