"Her wealth is big."
Traduction :Sa richesse est grande.
As a native English speaker, I would never say "her wealth is big". But, it is simple English, and most people would understand what you mean to say.
Instead I would use variations of "immense fortune".
- Her fortune is immense.
- She has an immense fortune.
- Her father left her an immense fortune.
- Despite his immense fortune, he is not happy.
I would also say:
- Despite his immense wealth, he is not happy.
The term "huge wealth" is used, though where I live we wouldn't say "her wealth is huge".
Some examples about the wealth gap (wealth inequality):
- China has a huge wealth gap.
- the causes and consequences of this huge wealth gap
- In the USA the already huge wealth gap between whites and non-whites is growing.
- There is a huge wealth gap between the poorest families and the richest.
Some examples about amassing, generating, creating and gaining huge wealth:
- Australian Mining Boom Generates Huge Wealth
- How to Create Huge Wealth With Little Risk
- Carlos Slim is Mexican, and he was able to amass huge wealth through a monopolistic control of telecommunications in the country.
- Relatives of China's top leaders often trade on their political connections to amass huge wealth.
- ... young Russian billionaires, between 40 and 50 years old, have gained huge wealth.
- Through their travels, raids, and conquests, the Vikings gained huge wealth.
You can also use the term in non-financial contexts. Two examples are wealth of knowledge and wealth of data:
- In almost all business sectors, there is a huge wealth of knowledge trapped within people.
- The teaching was of the highest level. Lecturers and tutors obviously possessed a huge wealth of knowledge within their particular field.
- The spacecraft lander's batteries are expected to last just 64 hours – that should be enough for scientists to gather a huge wealth of data.
- Facebook will now be able to tap into a huge wealth of data about real-time social interactions (when Facebook bought WhatsApp)
Using 'precisions' here sounds unnatural. I would use 'clarifications' instead.
l'opératrice ne peut-elle pas faire un (gros !) effort de prononciation !! Faute de contexte, il est souvent difficile de comprendre ce qui est dit. Ici par exemple, j'ai entendu 'her wall is big" , ce qui peut aussi faire sens !
