With most verbs, if they're in the past tense or past participle, they end with "ed,"

00:18

and that's all there is to it. For example… [Eggs frying]

00:21

If you did some work, then you worked.

00:23

If you used headphones to listen to music, then you listened. [Girl listening to music]

00:26

If you found those last two sentences boring, then you were bored.

00:29

And we're a little offended, but we'll get over it.

00:32

However, some verbs are like that one kid who insists that he doesn't double dribble– [Boy dribbling a basketball]

00:36

–they just refuse to play by the rules.

00:38

When verbs have all sorts of different endings, we call them irregular verbs. [Dino teaching irregular verbs]

00:42

Not like how your grandpa is irregular, for the record, so don’t bother with the prune juice.

00:47

Anyway, let's take a look at a few. Lisa went to a jewellery store, and saw a [Lisa walking into a jewellery store]

00:51

set of earrings she liked.

00:52

If she wanted to select that pair in the past tense, that'd be easy. "Select" is a regular

00:57

verb, so we'd just add "ed" to the end, and say: "Lisa selected a pair of earrings."

01:02

But if we wanted to use the verb "choose," things would be different. [Coop pointing to the word choose]

01:06

We can't just add a "d" to make "choosed.”

01:08

Well…we could, but then people would snicker at us behind our backs, so we choosed to not do that… [People laughing at Lisa]

01:13

Instead, since "choose" is an irregular verb, we use its very specific past tense form:

01:18

"chose." So we say: "Lisa chose a set of earrings."

01:21

Either, way Lisa is a gal who knows what she wants, and we appreciate that about her.

01:25

Anyway, when Lisa tries the earrings on, she likes them, but she also sees that they're [Lisa wearing the earrings]

01:30

way too expensive.

01:31

And guess what? "See" is also an irregular verb, so if we want to use it in the past

01:35

tense, we can't just throw a "d" on the end and call it a day.

01:39

Again, we need to find the specific past tense form of "see": "saw." [Girl and boy on a see-saw]

01:43

Hehe, seesaw.

01:44

Anyway, the right sentence here would be: "Lisa saw that the earrings were way too expensive."

01:49

Gotta learn to check that price tag first, Lisa. [Lisa looking sad at the price tag of the earrings]

01:52

Throwing caution to the wind, Lisa decided to buy them anyway.

01:55

How daring. Or irresponsible. This isn’t a personal finance lesson, so we’ll leave [Person sitting in a bank]

01:59

that judgment call up to you.

02:01

Anyway, sensing a pattern?

02:02

"Buy" is an irregular verb, so following it up with "ed" just won't cut it.

02:06

Instead, we need the specific past tense form of "buy" which is "bought." [Dino teaching past tense verb of buy]

02:10

That means we say: "Lisa bought the earrings."

02:13

Good for you, Lisa. You work those earrings. Unfortunately, being irregular and all, there

02:18

aren't any quick and easy rules to figure out the past tense or past participle forms [Person atop a mountain]

02:23

of the various irregular verbs.

02:24

Consulting a chart is really your best bet, or just, you know, cramming ‘em all in that

02:29

big ol’ brain of yours. [Boys head opens and charts go into his head]

02:31

Irregular verbs can be a bit tricky, but hopefully you finded them interesting.

02:34

Or, rather, hopefully you found them, uh… [Girls laughing at boy in school hallway]

02:37

Okay. Maybe we need to watch this video again…
