gday guys.

Im looking at the nouns used in the いadj and なadj.

I won't say this with 100% confidence - not by a long shot (n5 here).

I'm noticing the nouns in the:

*なadj are all like 'abstract nouns'. And the 

*adj seem to use many nouns that are closer to 'concrete nouns'. 

Even when similar words like "wide" etc

*いadj appears (to me) to refer to something more physical or a thing.

*なadj (to me) seems to more abstract.

Is there some sense to that, at least in proper grammar terms?

question
i-adjectives wago-and-kango
concrete nouns and abstract nouns. いadj　なadj
Yes, your observation is basically correct. Most na-adjectives are based on
[Sino-Japanese words](https://en.wikipedia.org/wiki/Sino-Japanese_vocabulary)
(aka _kango_ ), which are words borrowed from China along with kanji, whereas
most i-adjectives are etymologically truly native to Japanese ( _yamato-
kotoba_ or _wago_ ). Naturally, many i-adjectives are simple and fundamental
ones like 大きい ("big"), 赤い ("red"), 重い ("heavy"). On the other hand, na-
adjectives tend to be difficult, abstract or technical ones, because such
words were not necessary in ancient Japan :-)

Sometimes the same concept can be described using both an i-adjective and a
na-adjective. For example an i-adjective
[鋭い](http://jisho.org/word/%E9%8B%AD%E3%81%84) ("sharp") means roughly the
same thing as a na-adjective [鋭利](http://jisho.org/word/%E9%8B%AD%E5%88%A9)
("sharp"). In such cases the na-adjective version tends to sound more
technical, stiff or formal.

Similar thing can be said for suru-verbs and "normal" verbs. While normal
verbs cover most of the day-to-day verb usages (e.g., 歩く "walk", 食べる "eat"),
most suru-verbs are kango and can describe more advanced or abstract concepts
(e.g., 運転する "drive", 保証する "warrant").
