In English, you can create the possible form by adding "can" or "able to" before the verb, and the verb itself does not change.

- Add ``can do ~'' at the end
Change “~ru” to “~areru”
Verbs that end in ``ru'' such as ``eat'' and ``see'' become possible forms by changing ``ru'' to ``areru.'' Similarly, other verbs such as ``see,'' ``wear,'' and ``sleep'' become possible forms if they are ``seen,'' ``wearable,'' and ``sleep.''
English | Basic form | Possible form |
eat | eat (taberu) | edible (taberareru) |
see, look, watch | see (miru) | seen (mirareru) |

"Ranuki words" are also often used.
"Ra-nuki words" are possible expressions that remove the "ra" from "edible" or "seen" to become "edible" or "seen." Although ra-nuki words are not grammatically accurate, Japanese people often use them in daily life.
Change “~u” to “~er”
Verbs that end in ``u'' (when written in Roman letters, the final character becomes ``u''), such as ``speak'' and ``write,'' can be created by changing the ``u'' part to ``eru.'' It can be shaped. For example, if you want to "speak," change the "u" at the end of "hanasu" to "eru," and it becomes "hanaseru." Similarly, ``write,'' ``drink,'' and ``take'' become possible forms if they are ``written,'' ``drinkable,'' and ``taken.''

talk, speak | speak (hanasu) | able to speak (hanaseru) |
write | write (kaku) | be able to write (kakeru) |
