Make sense of what you’re practicing
Know the verb group
Ichidan verbs drop る before most endings. Godan verbs change their final sound. 帰る (かえる, return) is godan despite ending in eru; dictionary classification matters more than a spelling shortcut.
Irregulars deserve attention
する becomes します and できる; 来る changes its reading to き or こ in several forms. 行く has the exceptional te-form 行って. ある becomes ない in the plain negative.
A form is not a whole meaning
The non-past can describe habits or future actions. 〜ている may describe an ongoing action or an enduring state. Read the sentence around a form to understand what it means.
