What is the difference between “oishii” and “umai”?
So what is the difference between the two?
“Oishii” is a common way to say and used by men and women of all ages. “Umai” is more casual than “oishii” and is used in casual situations, and it sounds like a masculine way of speaking.
But some women also use it when speaking with friends or on SNSs, in which case their way of talking sounds less feminine.
Of course, “Oishii” is used in a formal place, but there are many cases where it sounds OK that a man says “umai”.
If you are in Japan, just remember to say “oishii”.
Both are used in a similar sense, but the meaning could be different because of the difference mentioned above.
For example:
“Oishii hanashi（おいしい話（はなし））”
A deal which sounds profitable with favorable condition
“Umai hahashi（うまい話（はなし））”
A deal that sounds too good to be true
By the way, examples of the words that mean the opposite of “oishii” and “umai” are “oishiku nai（おいしくない）”, “mazui（まずい）” and so on.
What is the origin of “Oishii”?
From the Muromachi era, there was a noun “ishi” the meaning of which was “excellent”, “superb” and the like.
Then it became an adjective “ishi-i”.
It was used mainly by women, which was meant “delicious”.
They started saying “oishii” with the prefix “o” to sound more politely.
Therefore, “oishii” can be technically separated into o-ishi-i.
When expressed using kanjis, it is “美味しい”.
“美味しい” is a combination of kanji and kana, and these are substitute characters in order to mean “delicious”
“美（び）” expresses “beauty”, “味（あじ）” expresses “taste” and I think it is a good choice of letters.
What is the origin of “umai”?
The origin of “umai” is also “delicious”, but the original meaning is “a ripen fruit becoming sweet”. It is said that “sweetness” meant “delicious” in Japan hundreds of years ago. I have heard that “tasty” is considered a “taste of salt” in Europe.
It is an interesting cultural difference.
