most satisfactory; quite enough; couldn't be better
Colloquial expression meaning something is more than satisfactory, often with a nuance of being grateful or pleasantly surprised. Used in phrases like 御の字だ or 御の字です.
If my salary goes up, I'll be more than satisfied.
At this price, this quality is quite enough.
十分 means 'enough' or 'sufficient' in a neutral sense. 御の字 implies not just sufficiency but a high degree of satisfaction, often with a grateful tone.
Standard kanji spelling. The kanji 御 is read おん here, not ご.
Irregular kanji usage. 恩 means 'favor' or 'grace', and this spelling is sometimes used to emphasize the nuance of being grateful or more than satisfactory.
Kana spelling is common in casual writing and avoids the unusual reading of 御.
The expression likely originates from the idea that the character 御 (おん) represents something honorable or highly valued, so being 'the character 御' means something is top-notch. The exact historical derivation is uncertain.
