Function of 「masu-stem」＋よる in Kansai-ben


Several years ago an acquaintance introduced me to the Hiroshima dialect and
mentioned clear distinction between perfect and continuous aspects:

Example 1:

> The bus is coming.  
>  Standard: バスが来ている。  
>  Chugoku: バスが来よる。  
>
>
> The bus has already arrived.  
>  Standard: バスが来ている。 -- same as above  
>  Chugoku: バスが来とる。

Example 2:

> When I got up this morning and opened the window, it was raining. (still
> raining)  
>  Standard: 今朝起きて窓を開けたら、雨が降っていた。  
>  Chugoku: 今朝起きて窓を開けたら、雨が降りよった。
>
> When I got up this morning and opened the window, I found it had rained.
> (already stopped.)  
>  Standard: 今朝起きて窓を開けたら、雨が降っていた。  
>  Chugoku: 今朝起きて窓を開けたら、雨が降っとった。

Now living in Kansai, I hear verbs like 言いよる, 来よった, 当てよった quite often, but so
far assumed it was regional variation of past tense: 言っている, 来た, 当てた.

Now that I looked at the explanation of Hiroshima-ben, I started to wonder if
this tense distinction was present in Kansai area too?

Is it archaic and getting extinct now because of hyōjungo prevalence?

Or maybe 「masu-stem」＋よる does have different function in Kansai-ben?




As you noticed, the auxiliary verb
[よる](https://kotobank.jp/word/%E3%82%88%E3%82%8B-406886), used in the form of
"連用形＋よる", mainly in the western part of Japan, has two different functions.

One is よる used to form the progressive form, which corresponds to ～ている in 標準語:

>   * 「今、なにしよるん?」「勉強しよるんじゃ。」 (広島弁)  
>  ≒ 「今、なんしょーん?」「勉強しょんじゃ。」 (contracted 広島弁)  
>  ≒ 「今、何しているの?」「勉強しているんだ。」 (標準語)  
>  ≒ "What are you doing now?" "I'm studying."
>

Another usage of よる is related to accusation, surprise, or just plain
emphasis. This is partly similar to
[～やがる](http://dictionary.goo.ne.jp/leaf/jn2/221163/m0u/) used also in slangy
標準語.

>   * うわ、ほんまに来よった! (大阪弁)  
>  ≒ うわ、本当に来やがった! (標準語)  
>  ≒ [accusingly/surprisingly] Wow, (you/he/they) _did_ come! (although it was
> not expected)
>   * 宝くじが当たりよった! (大阪弁)  
>  ≒ 宝くじが当たった! (標準語)  
>  ≒ I won a lottery! (not "I was winning ...")
>

I believe this kind of よる is not related to tense in any way.

Another example:

>   * あいつ、嘘を言いよった。(mainly 大阪弁)  
>  ≒ [accusingly] He told a lie!
>   * それ、ママがいつも言いよった。(mainly 中国四国方言)  
>  ≒ My mom was always saying that. (past progressive)
>

( **EDIT as per the comments below:** The 'progressive' usage of よる may be
specific to 中国四国方言 including 広島弁, and I am better at it than 大阪弁. See this
[Wikipedia
discussion](https://ja.wikipedia.org/wiki/%E4%B8%AD%E5%9B%BD%E6%96%B9%E8%A8%80#.E6.96.87.E6.B3.95).
I removed the word 関西弁 because it is ambiguous and [may or may not include
中国方言](https://ja.wikipedia.org/wiki/%E9%96%A2%E8%A5%BF%E5%BC%81).)

I'm afraid I don't know whether 大阪弁 actually distinguishes between the perfect
tense and the past tense in some way.
