The correct spelling of the phrase "more far extending" should be "more far-reaching". The /r/ sound in "far" is pronounced with a retroflex approximant, which means the tongue curls back slightly. When adding the suffix "-ing", the final "g" is pronounced as a voiced velar fricative /ɡ/ sound. To indicate emphasis, we add the word "reaching" after "far" to create an adjective meaning "extending to a greater distance or degree". The correct phonetic transcription would be /mɔːr fɑːr-riːtʃɪŋ/.
