22.2.1 irregular in writing, regular in the pronounciation
We are going to list now some verbs which change in writing because some letters (gi = /dshi/ - ghi = /gi/, ca = /ka/ - ci= /tschi/ etc.), change their pronounciation depending on the following letter. In this case sometimes the writing is "irregular" to keep the pronunciation regular. The examples just show how the thin books you find on the market are organized, we are not going to show all the existing irregularities.
