Grammar II - 13.01
Potential Verbs
  Potential verbs are used to say that someone "can" or "has the ability to" do something, or that something is possible
  Constructing potential verbs:
  ru-verbs: 
  Drop the final -ru and add -rareru 
見る -> 見られる to see, to watch - seeing is possible

miru - mirareru

 
  u-verbs: 
  Drop the final -u and add -eru
行く -> 行ける to go - going is possible
iku - ikeru  
   
  Irregular verbs: 
くる -> こられる to arrive - arriving is possible
kuru - korareru  
する -> できる to be - to be able to
suru - dekiru  
   
  Alternative potential forms: 
  (drop the ra from rareru, only for -ru verbs)
出る -> 出れる

to leave, to exit - exiting is possible

deru - dereru

 
見る -> 見れる to see, to watch - seeing is possible

miru - mireru

 
くる -> これる to arrive - arriving is possible
kuru - koreru  
   
 

Potential Verbs themselves conjugate as regular ru-verbs.

  Those verbs that take the particle wo [o] can take either wo [o] or ga when they have been made into the potential.
dekiru (able to do), the potential counterpart of the verb suru (to do), is somewhat special, and takes ga almost all the time.
(The use of wo [o] with dekiru is considered highly substandard.)
All particles other than wo [o] remain the same when the verb is turned into the potential.
