I need some help understanding the grammar of しのげそうな in この寒さをしのげそうな防寒服を手渡され


I can understand the gist of what the below sentence is saying; but the part
in the first section that's only hiragana (bolded part) is confusing me.

> この寒さを **しのげそうな** 防寒服を手渡され、それを着込みながら僕は彼女に質問した。

I _think_ that the そうな is a そう+な-particle, but seeing as how I don't know what
the しのげ that comes directly before it is, I could easily be wrong in my
understanding of what the そうな hiragana in the above sentence actually means.

I am unable to tell if the の is a particle の, or is a part of a しの-stem/しのげ-
stem, which presents another issue. I've tried looking up the 'usage of げ'
under the assumption that しのげ is a しの-stem + げ, but nothing I found helped me.
I did find [this
answer](https://japanese.stackexchange.com/questions/1386/what-is-the-usage-
of-%E3%81%92-and-how-does-it-differ-
from-%E3%81%9D%E3%81%86-or-%E3%81%A3%E3%81%BD%E3%81%84), but I believe it
served to only confuse me more as the first answer says that "...this makes 〜げ
more subjective whereas 〜そう is more objective..." which means that in my
sentence they are contradicting each other?

Looking on Jisho.org gave me no results for しのげ, and a few for しの; but I still
don't know what the げ is used for?




そうな is indeed そう + particle な, where the な here is the same noun-modifying な
as in 綺麗な or 静かな.

しのげ is the stem of しのげる, the potential form of verb 凌【しの】ぐ, "to get through
something, to endure something, to put up with something".

So しのげそうな =

  * しのげ "can get through, can endure"
  * そう "seems like"
  * な (modifier particle)

Looking at the first half of your sample text:

> この寒さをしのげそうな防寒服を手渡され、

"This cold" is what the verb 凌ぐ takes as its object, and here that phrase
modifies the 防寒服【ぼうかんふく】.

> この 寒さ を しのげそう な 防寒服 を 手渡され、  
>  This cold `[OBJ]` can-endure-seems `[MOD]` against-cold-clothes `[OBJ]`
> hand-transferred →  
>  I was handed heavy winter clothes that seemed like they could stand up to
> this cold, ...




しのぐ (dictionary form) "to endure"/"to stave off"/"keep out" etc..この寒さをしのぐ =
keep out this cold.

しのげる = potential form of しのぐ = able to keep out

しのげそうな = attributive form of そうだ added to masu-stem of verb = seem to be able
to keep out.
