Romaji are great, and in some ways more instructive because they reveal patterns which are otherwise a little hidden. You just have to realize that S+I is shi, T+U is tsu, etc. I don’t want to get too deep into it but there is a regularity to the language, and rules, and different choices of writing system reveals different pieces of the puzzle.

Next, the conjugation itself. There are massive categories of conjugations missing! Like, how do you get from taberu / nomu in this system to tabereru / nomereru? It turns out that these ichidan and godan verbs actually do have some differences in conjugation. Who’d have thought? (There is the -i stem, but there are other forms.)

Both of these things are described in the article. The first one is in “why romaji is actually bad” section, the second one is in “one more thing” part at the very end.
