Now, I don't know whether I really need a printed dictionary either. As an English learner who is trying to become the advanced level. I have to say the words and usages in your writing is advanced level and some of them is a challenge for me to understand. But overall, it is a good material to learn from. And because, by using a computer, I have the software (application) that helps me to translate instantly. Thank to the apps which can help to turn the difficult job into a acceptable one. From my experience, Instead of printed dictionary, I prefer to use the online dictionary or search answers online by using computer with the instant translator, in case there are something need to be translated instantly. And not only the translators is useful but also I can use computer to save and organize all the related English problems, grammars in a document by just copying and pasting, and most importantly I can find back what I want or half-remembered things by searching the well-organized documents directly. I think that is why, as a English learner, I think it is more convenient for me to use computer and online sources to learn English. Hope it will be helpful for you. Best wishes to you, too.

Dear Michael Thank you so much for your time and effort. What you said is really helpful. --- Especially, 1. "A book of Michael's.= Michael's book " 2.That is a book of Michael => it contains Michael's writings. exception : He's a friend of Michael. (completely acceptable) --- Thanky you for eliminating the flawed sources. It actually help me correct and slove the confusing questions. I will redirect and focus more on the authoritative source like Cambridge dictionary. I will also try and challenge wordreference.com as you suggest.

Hello. Dear Michael thank you for sharing lots of informative references with me. It helps a lot. I usually just search answers online directly, because it seems like answers could be found easily and conveniently. ---- The following three Online dictionaries I often use relate to your references but it's online and free version, Cambridge English dictionary Oxford English Dictionary Merriam Webster dictionary -- longman online dictionary (I mostly use it.) --- But I think I will buy them, when they are affordable to me.

Dear Michael: Thank you for your help. Sorry for the late reply, it really takes time to serarch/read enough information from grammar websites. (a) I found the sentenc (2) could have double meanings [includeing both meaning (a) and (b)], based on the website provided by you below. --- https://www.quickanddirtytips.com/education/grammar/double-possessives?page=1 it says: "This is Marie's portrait," you end up with an ambiguous sentence that could mean you are looking at a portrait of Marie or a portrait that is owned by Marie. -- (b) I also found the rule of the usage about "of─possessives" is conflicting. Rule (1): When we are talking about things that belong to us, we usually use ’s (we don’t use "of".) https://dictionary.cambridge.org/grammar/british-grammar/possession-john-s-car-a-friend-of-mine However, I find the examples from the other three grammar websites conflict with the rule(1). The conflict is really confusing. - 1. the car of John = John's car https://www.ef.com/ca/english-resources/english-grammar/forming-possessive/ 2. The feet of Jaime = Jaime's feet https://grammar.yourdictionary.com/style-and-usage/english-grammar-usage-possessives.html 3. (the third website) It says "The commonly repeated "rule" that you can "only use 's with people" is quite wrong. It is a very broad generalisation, and there are lots of excep­tions." from: https://linguapress.com/grammar/possessives.htm

Thank you, Michael, for your nice explanation. Thank you,, Phil, for your correction and the good intention to help solve the follow-up questions.

Dear Micael: Thank you for your kind reminder. I think I must avoid the similarity by adding or change some words.
