Hi. Welcome back to EngVid. I'm Adam; nice to see you again. Today's lesson is for Suhaib,

who requested this lesson from Facebook. We're going to look at phrasal verbs with the verb
1
10780
6130
00:16
"knock". I know all of you know this verb, "knock" – "Who's at the door?", etc. When
2
16910
7000
00:24
we combine it with other prepositions to get phrasal verbs, the meaning is completely different.
3
24550

00:30
We're going to look at a few of these. We're going to look at "knock down", "knock over",
4
30159
5821
00:35
"knock up", "knock out", and "knock off". These are verbs. Of course, we have "knockout"
5
35980
8515
00:44
and we have "knockoff" as nouns – could be adjectives as well. Let's start.
6

00:52
"Knock down": What does it mean to "knock down"? Well...
7
52080
3988
01:00
I have a domino, let's say, standing
8
60279
3011
01:03
up here on the table. I "knock it down", I topple it, I make it fall. Very simple, "knock
9
63350
7000
01:10
down" – make it fall. Easy.
10
70406
3374
01:13
"Knock over" is basically the same thing. You can "knock something over". For example,
11
73780
5890
01:19
you're walking in a restaurant, you're not paying attention, you bump into a table, you
12
79670
4890
01:24
"knock over" their wine glass, spill it on their dress. Not very happy, don't do that.
13
84560
5099
01:29
Be very careful. "Knock down" and "knock over" – the difference is that this is on purpose.
14
89659
5841
01:35
This could be accidental. So try not to do that.
15
95500
4710
01:40
"Knock up": This is a little bit different than what you may expect. It doesn't have
16
100210
6350
01:46
anything to do with lifting, with raising, anything that you can imagine. Some of you
17
106560
5580
01:52
may have heard this in movies and in Hollywood. There's actually a movie called 'Knocked Up'.
18
112140
6300
01:58
This means make someone pregnant. Yes, make someone have a baby. To "knock someone up”
19
118440
7000
02:06
is to get a girl pregnant. If she is "knocked up", that means she is pregnant. Very, very
20
126000
7000
02:13
much slang, not an everyday word that you're going to use.
21
133470
5720
02:19
"Knock out": Some of you might like sports. If you like boxing, you know this word. If
22
139190
6140
02:25
you like hockey, you know this word. To "knock out" means to punch and put unconscious; that's
23
145330
6720
02:32
one meaning. Another meaning basically means to put out of order. For example, there's
24
152050
11192
02:43
a lightning storm. Lightning comes down from the sky, it hits the electrical wires of a
25
163340
5840
02:49
city, it "knocks out" electricity to many houses. So to "knock out" – to put out of order,
26
169180
8135
02:57
to put out of commission.
27
177430
2169
02:59
"Knockout" has a completely different meaning from "knock out". You have to be very careful.
28
179599
6890
03:06
Notice there is no space between the words. It's one word. "Knock out" – two words.
29
186489
8949
03:15
Verb -- and adjective or noun. If you say about someone, usually a woman, you don't really
30
195558
9425
03:25
say this about men, although you could. If you see a woman walking down the street and
31
205120
6199
03:31
you say, "Wow. What a knockout.", what that means is she's gorgeous. She's so beautiful
32
211319
6161
03:37
it's like getting a punch in the face. You want to fall down because you're in love,
33
217480
3520
03:41
or lust, or whatever you are in. A "knockout" – a very gorgeous person, or gorgeous. Good.
34
221000
8549
03:49
"Knockoff": Again, you can "knock" something off the table, but it could also mean steal.
35
229700
7000
04:00
There are some countries that specialize in "knocking off" other countries' products.
36
240148
7361
04:08
These fake products are called "knockoffs". So basically "knockoff" means fake. You could
37
248919
7722
04:16
go, for example, traveling in some country and you see a Louis Vuitton bag, but this
38
256697
6243
04:22
Louis Vuitton bag is only $50. You're thinking, "Wow. What a bargain. I'm very lucky today.
39
262940
6960
04:29
I get a Louis Vuitton bag for $50, or a Gucci bag for $50." Be careful – it's probably
40
269900
6690
04:36
a knockoff. That's a noun. It means fake, not real. You don't actually have a Louis
41
276590
6770
04:43
Vuitton bag, you have a Joe Schmoe bag with Louis Vuitton written all over it. You're
42
283360
5960
04:49
lucky… but not so lucky. Very simple; very easy words. My example is gone. Sorry. I'll
43
289320
12062
05:01
come back to it.
44
301650
1340
05:02
I bumped into the table and knocked over someone's wine. I didn't want to, but I knocked up my
45
302990
5590
05:08
girlfriend, now I have to marry her because I'm a responsible guy. The lightning knocked
46
308625
5530
05:14
out electricity to the entire city. Be careful that you don't get a knockoff, because some
47
314110
6300
05:20
countries like to knock off other countries' products. "Knock down": If you're really angry,
48
320410
6720
05:27
you can knock me down and I won't fight back. Not the best example, but it'll work.
