Had and Was

Hello my fellow students. We've learned all about the past tense in Korean and I wanted to specifically talk about the past tense of two very important verbs it-da to have and i-da to be.
to have is conjugated the usual way cut off the da and add eo-sseo to make the casual form add eo-sseo-yo to make the polite form and add eot-seum-nida to make the formal form and that translates to had.
When we use the past tense of it-da in a sentence we need to use the same kind of subject marking particles we did with the present tense. Please watch my video on it-da in the present tense, if you haven't already. I'm actually rather proud of it. but like I was saying use the same kind of subject marking particles as we used with the present tense.
The subject gets a neun/eun, and the object gets an i/ga
for example I had a computer in the casual form would be
나는 컴퓨터가 있었어.
in the polite form it would be
저는 컴퓨터가 있었어요. and in the formal form
저는 컴퓨터가 있습니다.
and that's what you need to know about had.

Now i-da to be is conjugated irregularly in the present tense, but in the past tense it is conjugated pretty much like normal. cut off the da and add eo-sseo to make the casual form add eo-sseo-yo to make the polite form and add eot-seum-nida to make the formal form. and then the vowels combine so that the i-eo turns into yeo like so:  였어, 였어요, 였습니다
One thing about i-da is that sometimes when you add the ending you can chose not to combine the vowels. and keep it as 이었어,이었어요,이었습니다 if you wish. and in fact all your verb roots that end in i can be spelled without the combining vowels.
But the combined way is more commonly used. That is what I will always use on this channel
마시었어요 마셨어요
달리었어요 달렸어요
즐기었어요 즐겼어요
소리치었어요 소리쳤어요

when you make sentences with the past tense of i-da you do not use any object marker, and you do not put a space between your object and the verb. This is the same rules as we learned for i-da in the present tense. Here's an example of a past tense sentence with i-da.
나는 댄서였어.
저는 댄서였어요.
저는 댄서였습니다.

So not too many big surprises with it-da and i-da in their past form. But had and was. are two very important words and these verbs don't always follow conventional rules so I wanted to take out all the guess work for you.
Thanks for studying with me everyone annyeonghi gyeseyo.
