The correct spelling for the phrase "all thats" is actually "all that's". It is a contraction of "all that is" or "all that has". The apostrophe in "that's" represents the missing letters, which are the "i" and "h" respectively. This is also reflected in the International Phonetic Alphabet (IPA) transcription of /ɔːl ðæts/, where the "s" sound at the end is represented by the symbol "s" and the apostrophe is omitted. Proper spelling and phonetic transcription ensure clarity and understanding in communication.
