The difference between 詳しい and 詳細 when used adverbially or adjectivally


While I know that 詳しい and 詳細 both have unique meanings, there are some cases
where I am not able to tell the difference between them. Here are two I've
stumbled upon:

[code]

    Adverbially:
    我々の研究計画を詳しく述べた
    パイロットはその光景を詳細に述べた
    
    Adjectivally:
    彼はパーティーについて詳細な説明をした
    もう少し詳しい説明をしてください
    
[/code]

Is there a difference in nuance, or are they virtually the same?




As (I hope) you could tell from the pronunciations of the two words,
「[詳]{くわ}しい」 is a [大和言葉]{やまとことば} (an originally Japanese word) and
「[詳細]{しょうさい}」 is a Sino loanword.

As with most other pairs of the two classes of words, 「詳しい」 and 「詳細な」
basically have the same meaning and the 大和言葉 sounds more informal and less
technical than its Sino lowanword counterpart. Perhaps I should write the
former as "kuwashii" in romaji for this discussion because we are talking
about a spoken language whenever we are talking about 大和言葉. Japanese was only
a spoken language before the Japanese encountered the Chinese. You will keep
witnessing this important fact about the "ranks" of the words used in Japanese
for as long as you study Japanese.

Thus, there is virtually no difference in nuance, let alone in meaning,
between the two words when they are used either adjectivally or adverbially.
Needless to say, only 「詳細」 can be used as a noun in one word. The Yamato
counterpart of that would be two-word-long ---「詳しいこと」.
