Campus's and John Jones's (the surname alone is ambiguous) are preferred, though you will find sources which consider the 's unnecessary. Try this: add the 's if it is pronounced in speaking the word-- /'kæm pə səz/, /'djoun zəz'/.
The 's is incorrect at all times with the pronoun: its hat. It's' always means it is/has.
Thank you but I am not clear about what you said. Could you explain to me what you meant by "Try this: add the 's if it is pronounced in speaking the word-- /'kæm pə səz/, /'djoun zəz'/" . Could you give me an example where 's it is not pronounced. Also, I don't understand what these characters above mean! Sorry, is my computer acting funny or am I totally out of it?!
Thank you so much again
Hello Teacher! That was very helpful...Thank you very much. I've always gotten confused with the names ending with S or Z so it is great to know how it works. BTW the phonetic website is also great. Talk about being out of hah? I thought my computer was playing tricks on me!!!
Thank you very much
