Understanding 手のつけようがない


> 、...錠前破りの名人だって、 **手のつけようがない** 。  
>  Even expert lock breakers _can do nothing about it_.

This is my best effort at a translation from looking at example sentences
using 手のつけようがない on Weblio.

I can't find this phrase in my dictionary, but it did have 手の施しようがない with a
similar meaning.

1) Is there a good universal translation of these phrases that works in most
cases?

2) Is there are difference between the two phrases?

3) Is there a sensible grammatical breakdown of these phrases, or should they
just be learned as a set phrase? What does the verb つける mean in this case?




If you could not find them in dictionaries, that's because these are simple
combinations of:

  * [～ようがない](https://dictionary.goo.ne.jp/jn/148920/meaning/m0u/) "there is no way to ～"

...and either of the following two set phrases:

  * [手を付ける](https://jisho.org/search/%E6%89%8B%E3%82%92%E4%BB%98%E3%81%91%E3%82%8B) "to start working on something", "to undertake", etc
  * 手を施す "to treat (a diseased/wounded person)", "to try to fix (a serious trouble)"

Therefore 手を付けようがない is closer to "I don't even know where to start" or "I can
do nothing about it", whereas 手の施しようがない means "The patient/problem is helpless
no matter what". Sometimes they are interchangeable, but sometimes they are
not. For example you can say 手の付けようがないほど暴れる馬 but not 手の施しようがないほど暴れる馬 because
the horse itself is not sick.
