Korean Past Tense- Conjugating (ha-da) Verbs/ 하다 Verbs

WATCH THE LESSON: https://youtu.be/FLoqCK04y8E
This video is on how to conjugate HA-DA verbs into the past tense. Korean has three types of verbs and videos for the other two types are linked in the description. Ha-da verbs are easily identifiable because their infinitive form ends in ha-da. These verbs are very common. Ha-da means "to do" so you can add it onto the end of many nouns to make them into verbs. When we are making the past tense we change that ha-da ending into
했어 to make the casual form
했어요 to make the polite form
했습니다 to make the formal form
if you're not familiar with the concept of casual polite and formal language I have a video on that in the description.
We now have our past tense of to do... did.
Now you can make sentences by putting a noun in front and adding a subject marker. if you need a lesson on what a subject marker is and how to use it there is a video in the description. Here are some example sentences in the casual form, polite form, and formal form.
I did. 나는 했어. 저는 했어요. 저는 했습니다.
We did. 우리는 했어. 저희는 했어요. 저희는 했습니다.
Those people did. 그사람들은 했어. 그사람들은 했어요. 그사람은 했습니다.
Mom did. 엄머는 했어. 엄머니는 했어요. 엄머니는 했습니다.
Pikachu did. 피카츄는 했어. 피카츄는 했어요. 피카츄는 했습니다.

and like I said ha-da is the verb "to do" and it can also be the ending of many more verbs. Like these ones.

Try conjugating a few of them if you like and check your answers in the description. That's all for now my fellow students. Thank you for studying with me.

List Of (a) Verbs

Korean Past Tense- Conjugating (a) Verbs/ 아Verbs

WATCH THE LESSON: https://www.youtube.com/watch?v=BWjOuDZW5QM
This is a video on how to conjugate Korean (a) verbs into the past tense. There are 3 types of verbs in Korean: (ha-da) verbs, which have verb roots that end in (ha), (a) verbs which have verb roots that end in a syllable that contains (o) or (a), and (eo) verbs  whose verb roots end in a syllable that contains any vowel except (o) or (a).
You will find videos for the other two types of verbs in the description. LET'S LEARN OUR PAST TENSE CONJUGATION OF (A) VERBS.
The best way to memorizes verbs is in their infinitive form. That's the form that ends in (-da) and roughly translates to "to verb". For example: (an-da) "to hug", (ga-da) "to go", (bo-da) "to see". As I was saying, memorize the infinitive forms and then you can conjugate them into whatever tense you want. Today we will conjugate into the past tense. To do that ... first remove the (-da), then to the root verb you add a past tense ending. and here they are:
았어, 았어요, 았습니다
in order of most casual to most formal.
So we add these past tense endings to each of our verb roots. If the verb root ended in a consonant we are done. We've made the past tense! If the verb root ended in a vowel we need to combine the vowels. There are two possible vowels. They are (a) and (o).
If it is an (a) your two (a)'s combine into one. If it is (o) the (o) and (a) combine into (wa).
So that is how you make the past tense of an (a) verb. You need to memorize these endings and remember how to combine the vowels.
Now let's make sentences I hugged, I went, I saw.
the word for I is na in the casual form and jeo in the polite/formal form
So we add that in front of our verbs, and then we top it off with subject markers just like we did in the present tense. We can use neun/eun if we want to emphasize the verb or i/ga if we want to emphasize the subject. the neun and the ga are for subjects that end in vowels and the eun and the i are for subjects that end in consonants. If you want a more detailed explanation of subject markers that is linked in the description.
please use my list of a verbs to practice conjugating into the past tense and to learn vocabulary. /you'll be glad you did. You can find the past tense forms in the comments section to check if you did it correctly. enjoy my useful links in the description and jal gyeseyo my fellow students. Thank you for studying with me.
