In episode 76 of Fairy Tail, Gildarts said this to Natsu:

> 本気でそう思ったら、止め **やしない** よ。 _(honki de sou omottara, tome **yashinai** yo)_

Which was translated in the subtitle as:

> If that's what you honestly believe, I won't stop you.

I thought "I won't stop you" would simply be "tomenai yo", so I'm kind of lost
about what nuance the extra "+yashinai" conjugation carries. What kind of
negative conjugation is it?

question
conjugations particle-は negation renyōkei
What does the "〜やしない" conjugation mean?
I think "I won't bother to stop you" or "I don't bother stopping you" would be
more close.

And that "ra" might be "rya", but I don't know rya can be shortened to ra or
not.

**Edit** : above is my hypothesis about "ra", but after watching the anime
provided by Amanda S, I hear as "ya-shinai" too as other said in comments.

Regarding や-しない, I can't find in 国語 dictionaries, but JMDict and one
dictionary site named tangorin say that や is は and used as colloquial form to
emphasize negative (ない) sense.

And it has meaning like "I woulnd't", "I am afraid ... will", ...

As others have said, this is probably really ～やしない, which is transmutation of
～はしない. What this suffix does is usually one of two things:

  1. It makes the verb a topic (with は) and then negate it. This is used to bring up the event described by the verb and then saying it won't happen (or isn't happening, have never happened - you get the point). From the context, this seems to be what's mainly happening here, Gildarts says to Natsu: "Well as for stopping you (as you may expect or fear I would try to) - no, I won't do that".

  2. It's also often used when there seems to be little intention to topicalize the verb. In such cases, I think it's mostly used as a stronger and more passionate negative than the simple ～ない.

I'm assuming that 止めりゃしない was misheard as 止めらしない, where that りゃ is a
contraction of りや to りゃ.

Instead of 止めらしない it should be 止めやしない. I've seen it written and heard it said
as 止めりゃしない but I suppose you can consider that a "slang mistake" treating 止める
as a go-dan instead of ichi-dan. (止めやしない is more common).

止めやしない is [RYK(masu form)+や+しない], which has the same meaning as 止める(など)はしない
[RTK(plain form)+(など)+は+しない] "I won't do anything like try to stop you," so
you will hear both forms from time to time.

The りゃ comes in if it's a ラ行 godan verb because りや will contract to りゃ:
蹴りゃしない, which again is the same meaning as 蹴るなどはしない

Other examples with varying degrees of contraction:

逃げやしない (does not contract) == 逃げるなどはしない 行きゃしない==行きやしない (sometimes contracts)
== 行くなどはしない 蹴りゃしない (always contracts) == 蹴るなどはしない

However, the entire construction is fairly rare when it's not 止めやしない, the
sheer frequency of that words use probably contributes to the "incorrect
slang" version of 止めりゃしない
