The spelling of the word "pre pares" seems confusing at first glance, but it can be explained using the International Phonetic Alphabet (IPA). The first syllable, "pre," is pronounced as /prə/, with a schwa sound followed by the consonant blend /pr/. The second syllable, "pares," is pronounced as /pɛərz/, with a long vowel sound /ɛə/ and the final consonant blend /rz/. So, despite the unusual spelling, "pre pares" can be broken down into two phonetically spelled syllables.
"Pre pares" is not a commonly used phrase and does not have an established etymology. However, if we break down the term, "pre" is a Latin prefix meaning "before", and "pares" is a Latin word meaning "equal". So, we can interpret "pre pares" as "before equals" or "prior to equals". It is possible that this term has been coined in a specific context or could be a play on words using Latin roots.
