お+(stem/base2)+になる is honorific (keigo).
掛けてください (polite, neutral, request)
お掛けください (very polite, neutral, request)
お掛けになってください (very polite, respectful, request)
お掛けになりませんか (very polite, respectful, invitation)
So I can use this for most verbs?
As for the honorific form "お + pre-masu form of Japanese origin verbs + になる", "ご + stem of Chinese origin -suru verbs + になる", mostly yes. It can be used for most verbs. But there are some exceptions.
1)verbs of one mora pre-masu form(ichidan verbs and irregular verbs)
いる, 着る, 煮る, 見る, 来る, 得る, 寝る, 経る,,,
2)loan words, mimetic words
プレーする, セットする, どきどきする,,,
3)some Chinese origin -suru verbs
運転する, 勝負する,,,
Further, those four structures do not always work well. Some could sound weird depending on the types of verbs or context.
Also I see you mention "食べる <--> 食べられる", but I thought られる was the potential form (eat vs can eat)? Is this similar to English then, like "can you go out tonight" vs "will you go out tonight'?
Thanks!
Ah, no, not the potential but the passive form. They are the same in ichidan verbs, though.
e.g.
食べる(ichidan) <--> 食べられる(potential/passive/honorific)
書く(godan) <--> 書かれる(passive/honorific), 書ける(potential)
