まけんわい

まだまだチビどもにはまけんわい
What is まけんわい? More specifically what is the わい part doing?

I've got some more questions.

ドラゴたちとずっとケンカごっこしてたんだよ

What is the ごっこしてた part?

オケラさまのおとおりだーい

What is おとおり and what is the い for?

おもいでとおもいでがおもいだしあっておもいでになっていくのです

What is the あって? It may be something simple but this hiragana and the sentence in general is messing me up xD

Thanks in advance.

～わい is apparently something like ～よ or ～だよ in 伊予弁. (まけん = 負けない).

ケンカごっこ - anything + ごっこ is "a game of make-believe X" (except for some special cases like 鬼ごっこ). The following is just normal する. It can refer to actual play by kids or I've seen it sarcastically (derogatorily?) used to suggest someone isn't doing something seriously - 報道ごっこ towards a news channel, for example.

お通り here may mean "coming through" /"make way for". だい is another ending particle (think it's just だ-like here) being stretched out for emphasis.

思い出し合って - e.g. the memories are coming together. I think. It's not just you, there need to be a few less おもいで in that sentence.

In addition to nekojita-san's excellent explanation, わい is relatively widely used in western Japan, such like Chūgoku region, not only in Iyo. In fact, せんわいや means しないよ in my home town.;-)

"The -masu stem of a verb + 合う" means "to do mutually" (e.g. 助け合う "to help each other").

Ahh thank you both. Very helpful and interesting answers, thanks!

So is the last one..."You (subject, people) recall and combine memories with memories that then go on to become memories"? ていくstill gets the better of me sometimes and this sentence is just urgh lol.

Yeah, it's sort of literary expression.

I see. Thanks again
