The spelling of the word "more semi" is quite unusual, but it can be explained through the International Phonetic Alphabet (IPA) transcription. "More" is spelled with the /mɔr/ sound, which is pronounced with an open back rounded vowel. "Semi" is pronounced with the /sɛmi/ sound, which has an open-mid front unrounded vowel. The combination of these two sounds creates the spelling of "more semi," which is used to describe something that is partially or somewhat more than something else.
