What is the difference between 〜るも and 〜ても


In grammar textbooks I see the 〜ても pattern clearly defined, but recently I've
encountered a similar usage of も that I can't find a good explanation for.
Here are two examples:

> 国民栄誉賞を打診されるもこれを固辞

(from the monologue at the start of a 僕のヒーローアカデミア anime episode)

> とりあえずググってみるも、どの機器がいいか分からない

(from a [RocketNews24 article](https://rocketnews24.com/2018/10/21/1128808/),
talking about being unable to find the right electric shaver)

Is this a casual pattern, or maybe an abbreviation of another pattern? From
context it seems similar in usage to 〜ても, or maybe even just 〜けど, but I'm not
sure of the nuance.




It is an old fashioned way of saying ても. In old Japanese, particles were
directly used after verbs' 連体形, without needing a nominalizer such as の or こと.
Nowadays, using a particle that way when it's normally used with a nominalizer
is considered archaic, so this construct is mostly used in literature or
formal situations.

The `dictionary form + も` behaves quite different from `te-form + も`.

Firstly, it is relatively more bookish. I don't mean you can't use it for a
casual topic, but you have to keep the sentence that contains this conjunction
in a detached style, like academic or journalistic writing. You can't use it
with final particles (ね/よ etc.). Using it in sentences with polite endings
(です/ます etc.) is not prohibited, but ですが or でしたが would be more suitable.

Secondly, the focus is different.

  * **X-ても Y** : _Y even (though) X_  
an expression that implies _X_ was what had near-highest expectancy not to end
with _Y_ , but still _Y_.

  * **X-るも Y** : _X, only to Y_  
describes that the result _Y_ is disappointing from the standpoint of someone
who did _X_. You can take it as a nuanced version of -けど and -が "but". _X_
always in dictionary form even if the event is past.
