the addition

[bhaisahab]

It would seem to me that "under addition" is far from being in common use, except amongst mathematicians and scientists. Obviously if you do a google search of it, you will get a lot of hits but that doesn't mean that its use is widespread in general English.

[Pedroski]

Did you not say it was 'completely wrong'? The mathematicians and scientists are completely wrong? Or they don't speak English?

I could google cook books, I suppose, but they are probably wrong too. I get 372 000 hits in 0.18 seconds. Here a few cookery examples:

and all of these can come in various flavours with addition of tomato, spinach and a variety of herbs

while pasta can be made a complete meal with addition of a few vegetables.

Tomato soup dresses up nicely with addition of spinach and pasta

ingredients consist of protein ...... under addition of vitamins, mineral nutrients, trace elements,

dumplings made under addition of yeast

Must be them damn foreigners a-writin' all that.

I agree, "under" is completely incorrect.

As you can see I was agreeing with Gilnetter that "under" was completely wrong in the context.
I haven't commented at all on the correctness of "the" in this thread.

[Pedroski]

Do you still think it is incorrect? If so, will you say why?

[Pedroski]

Just because it's on the Internet is no guarantee that it is correct.

I agree. The corollary, for me anyway, is, you saying it is incorrect does not mean that it is, in fact, incorrect.

This reminds me of a bridge under construction, doesn't it sound weird too?
Under, kind of implies "less", and, addition, "more". Is it almost like an oxymoron? It sounds strange, even to my incipient understanding. Is this correct?

Eager to follow your argument gentlemen.

"Under construction" is a common expression, used to talk about something in the process of being built.

I am here to learn the language.
But I can't learn the language by way of behaving like a parrot only. I usually think of how do I feel it at the moment, depending on the level of the knowledge, collected and developed.

On my first view, the sentence

Pasta's basic ingredients are flour and water, sometimes under addition of eggs or oil.

seemed strange to me.

Thinking of it I've become familiar with the sentence.
At length after the explanation I concluded that the phrase for example perfectly match chemical industry which should explain chemical processes between materials.

Under different ingredients these two materials react different.

"Under addition of these two ingredients" could also mean "under control of these two ingredients"

The preposition under doesn't always mean that something is covered with something else but the word under has a lot of meanings as a part of different phrases.

Thinking about the genuine sentence my conclusion is that "the addition of eggs and oil" is wrong.

Why?

Because "the addition of eggs and oil" means for me "the very strict ratio between them and the flour and water."
That is how I feel the matter.

But

My pasta's basic ingredients are flour and water and the addition of eggs and oil. This is OK for me.
The specified pasta uses the addition of eggs and oil.
Non specified pasta uses an addition of eggs and oil.

(In this sentence, "addition" is a noun, so it needs an article in front. (SUSIEDQQ))

Different people like to make different pasta with its specific ratio between the ingredients.

THANK YOU GUYS. I'M ON MY WAY TO SEE THE BRIDGE UNDER CONSTRUCTION. SEE YOU.
