/ʃɔː/ can you pls help me what word is this po?
/ʃ/ is called 'voiceless postalveolar fricative'. It is the shhh sound present in the beginning of words like shy, shore, she etc.
/ɔː/ is called 'open-mid back rounded vowel or low-mid back rounded vowel'. It is present in words like north, law, thought etc.
In rhotic accents, the /r/ sound is always pronounced so /ʃɔː/ in rhotic accents would be pronounced as /ʃɔːr/ (with 'r' sound).
In non-rhotic accents, the /r/ sound is not pronounced unless it precedes a vowel sound so /ʃɔːr/ becomes /ʃɔː/.
Generally, in General American the 'r' in /ɔːr/ is pronounced while in RP, the 'r' is not pronounced.
