Is there any rule relating to ㅣ+ㅓ = ㅔ notㅐ? If we change the order of the combination then it makes sense to have ㅓ+ㅣ= ㅔ.
I have just come across a list as below. I'd like to know if there is any rule for this or should we memorize them by hard?
ㅣ + ㅔ => ㅖ
ㅣ + ㅐ => ㅒ
ㅣ + ㅏ => ㅑ
ㅣ + ㅗ => ㅛ
ㅣ + ㅓ => ㅕ
ㅜ + ㅣ => ㅟ
ㅜ + ㅔ => ㅞ
ㅗ + ㅐ => ㅙ
ㅗ + ㅏ => ㅘ
ㅜ + ㅓ => ㅝ
ㅡ + ㅣ => ㅢ
Most of the time when combining vowels, the left side of the addition goes on the left side, and the right goes on the right. For example:
ㅗ + ㅏ => ㅘ
ㅜ + ㅣ => ㅟ
ㅡ + ㅣ => ㅢ
The list that you found is rather peculiar. Technically, the first 5 examples are deceiving. From what I'm deducing, you should treat ㅣ as a . or a small ㅣ. When a vowel already has a protruding little line, then adding the . or small ㅣ results in another protruding little line next to the previous one, making the vowel sound like it begins with a "y".
The reason why I'm referring to a . is because when Korean alphabet was first introduced, the protruding parts were referred as a dot like in the image below.
ㅗ + ㅏ ㅗ is left and ㅏ is right. However, we can also change the order of them ㅏ+ ㅗ ㅏ is left and ㅗ is right.
ㅡ, ㅗ, ㅜ will always go on the left side, the exception would be when you're adding another 'protrusion'. Because when writing Korean vowels, they go on the right/bottom side of the syllable. When you type in ㄱ + ㅗ + ㅏ you'll get 과, however if you type in ㄱ + ㅏ + ㅗ you get 가ㅗ. The 'rule' is derived from the order which things are written. Hope this helps.

y + ah = yah . + ㅏ = ㅑ Other than the example given, everything else follows the left is on the left pattern. Just keep in mind that the vowels that go on the bottom will not go on the right side unless the 'protrusion'.

When combining Korean character ㅣ with other vowels, it is always put at the end of the other vowel.
ㅣ + ㅗ => ㅛ is not correct, it is actually ㅗ + ㅣ => ㅚ
ㅣ + ㅏ => ㅑ is also not correct, it is ㅏ + ㅣ => ㅐ
like this ㅓ+ㅣ should be ㅔ
ㅣ+ㅏ => ㅐ but from the list it is ㅣ + ㅏ => ㅑ.
