  • Hi this is Tutor Nick P and this is Lesson 361. The title of today's lesson

  • is the difference between unseeable and invisible. Yeah. This is sometimes... this

  • question that comes up. They do sound like they're almost the same thing but

  • in this video I will try to clarify where we're more likely to use one then

  • the other one. So let's look at the note here. If someone says that something is

  • invisible, it means that it cannot be seen at all. Usually because it's

  • transparent. That's one of the main ways. That means you actually see through it.

  • Too tiny or hidden. Okay. Let's continue. If someone says that something is

  • unseeable , it is almost impossible to see usually because it cannot be perceived

  • with the eyes. The eyes can't tell that it's there. Okay. Let's continue. When we

  • use the word invisible to mean too tiny or hidden or we often use words like

  • almost because by its nature invisible usually means transparent. So if it's

  • just too tiny we say we often say that it is almost invisible or nearly

  • invisible. Because it's just so tiny that our eyes can't see it. So a lot of times

  • we will add a word like almost or nearly which we don't usually use with

  • unseeable. With hidden it because it became invisible.

  • Or if it is hidden, we might say that it became invisible because maybe something

  • covered it. All right. Let's go on. Invisible means it cannot be seen at all.

  • Unseeable does not mean it cannot be seen. It means it cannot be perceived. So

  • one cannot distinguish its actual form. Okay. The question came up with a topic

  • about black holes. Yeah. Yeah. Where recently I think NASA created a

  • computer-generated image around the black hole, so you could distinguish it.

  • But if they didn't do it , it would have been unseeable.

  • Okay. Black holes are not invisible. You still see blackness. So it's not

  • invisible. You just cannot distinguish where it

  • begins or you know, where it may end. So therefore, we say that it's unseeable.

  • Even though it's right there. But you can't see it because the blackness

  • around it looks exactly the same. In the same sense if a chameleon you know, like

  • a little lizard type creature chameleon changes his colors to blend in with a

  • background, he maybe unseeable. Again he wouldn't be invisible. He'd be right

  • there but in this case this is a case we would probably use unseeable. He's not

  • really invisible. Invisible by its nature is usually transparent. For example, a

  • poltergeist is a type of invisible ghost. Yeah. So we've seen this in movies and

  • we've also seen people have like videotapes where it seems like things are

  • moving around a room. You know, a chair may roll across the floor or computer

  • pops on. Or you've even seen papers fly out of a file or something like that.

  • With nobody there which would suggest that there is some force or possibly a

  • ghost in this case. This ghost would be called a poltergeist but you do not

  • actually see a form there. It's completely invisible. So if there is

  • something there and it's it's not some wind or other explanation to it, then

  • that ghost would ... that type of a ghost would actually be invisible.

  • You only can perceive, you only can understand or figure out it's there

  • because it's moving things with its force. Okay. So just like of course wind

  • and air. We know when it airs there. But you know unless wind or air has some sort

  • of another gas or another substance in it, we can't see it. It's invisible. We see

  • right through it. It is transparent. Okay. Well I hope this video helped to give you a

  • better idea when we would probably say something is unseeable and when

  • something is invisible because they , they, they can be tricky. Just by the nature of

  • how we talk about them. Anyway, I hope you got it. I hope it was clear. Thank you for

  • your time. Bye-bye.
