Hi Bob! So I searched the Internet for you, and found an excellent blogpost. Here's a quote: "So, here’s the rule: ● to hear: to perceive a sound (with the auditory senses). In other words, to hear is to perceive with your ears. Example: I heard an airplane fly overhead. Yes, we all know that one. It’s the next one that’s important. ● to hear of: to be aware of the existence of someone or something, specifically by being told of the existence of that person or thing by other people. [...] Compare these two sentences: ● "I’ve heard Bubba." This sentence means that Bubba made a sound, and you heard him. ● "I’ve heard of Bubba." This sentence means that you don’t personally know Bubba, but you’re aware that he exists because you’ve heard him discussed or mentioned by others. " If you want to read the full post, here's the link: www.urch.com/english/heard-vs-heard-of/ Hope it helped!

Hey Bob, Hear = 听见, 听到 (Did you hear me calling you? 你听见我呼唤吗？) Hear of = 听说过 (Did you hear of the new import regulations? 听说过新进口的规定吗？） Cheers

When I say to you : Did you hear the explosion ? I mean did you hear it , its sound .. but when I say to you : Did you hear of the explosion ? I mean did you hear any news about it .. ( like how many victims , injured ... etc ) hope this helped you :)

Examples can be as follows : "I heard about your mom" Meaning = It means "I was informed about an affair your mom is involved in." It could be that she was sick, died, was arrested, won the Pritzker Prize or whatever. "I heard of your mom" is less likely to be used. Meaning = If your mom used to be a famous singer, I could say "I heard of your mom (my parents like her music)."
