Why are some similar phrases are shown together and some are not?

[KuroNeko1313]

for example, 英和, 英語, 英文, 英国, 英会話 are all shown together for simpler memorization

whereas 卒業式 and 卒業する are shown separately even when they are unlocked at the same time

is this only me or does anyone else experience it as well?

would really appreciate any info on this subject

thanks in advance

As far as I know the lesson_position of each item determines the order in which the lessons appear. Here is a list of the three 卒業 items according to the API:

item	lesson_position	level
卒業	129	14
卒業式	122	16
卒業する	130	16

And here is the list for the items starting with 英:

item	lesson_position	level
英	32	15
英語	101	15
英会話	102	15
英文	103	15
英国	104	15
英和	105	15
英雄	125	29
英訳	141	32
英語圏	101	39

The 英-items are indeed all grouped, while 卒業式 and 卒業する are farther apart.

So no, it’s not only you.
