The correct spelling of the phrase "more representa" should be "more representative." The IPA phonetic transcription of this word is /mɔr ˌrɛprɪˈzɛntətɪv/. The first syllable "mor" is pronounced with an open-mid back rounded vowel sound /ɔ/, followed by the consonant cluster /r/ and the second syllable "re" pronounced with a short e sound /ɛ/. The word ends with the suffix "-tive" pronounced with the schwa sound /ə/ and the consonants /t/ and /ɪv/.
The phrase "more representa" does not have a standard etymology, as it is a combination of two words from different languages. "More" is an English word that means "additional" or "extra", while "representa" appears to be a partial form of the Spanish word "representación", which means "representation". The combining of these two words may have been done with the intention of creating a unique phrase or title.
