- Avoid translating directly as 'приток' for all contexts, as it's less used in casual English than in Russian. In business, 'inflow' is correct; for people, 'influx' is often more natural.
Common Mistakes
- Using 'inflow' as a verb (the correct verb is 'flow in'). Confusing 'inflow' with 'income' (income is specifically money earned).

FAQ
Frequently Asked Questions
It is primarily a noun. While technically it can be used as a verb, especially in technical writing, it is very rare and often sounds awkward. The phrasal verb 'flow in' is the standard verbal form.
They are often interchangeable, especially for people or things arriving. 'Influx' is more common for people and large groups (influx of refugees). 'Inflow' is strongly established in financial and technical contexts (cash inflow, water inflow).
The direct opposite is 'outflow' (e.g., cash outflow, outflow of refugees). Other antonyms include 'outflux', 'exodus', and 'departure'.
Yes, but it carries a slightly formal or technical tone. In casual speech about people arriving, 'influx' or simply 'lots of people arrived' is more common. For money, 'money coming in' is a more casual alternative.
