- Do not confuse with 'outcome' (результат). 'Outflow' is about movement/process, not result.
- Avoid direct calque 'выток' — use 'отток' or 'утечка'.
- The verb 'to outflow' is rare; prefer 'to flow out' or phrases like 'to cause an outflow'.
Common Mistakes
- Using 'outflow' as a verb where 'flow out' is more natural (e.g., 'The water outflowed' is awkward).
- Confusing 'outflow' (process) with 'outcome' (result).
- Misspelling as two words: 'out flow'.

FAQ
Frequently Asked Questions
Overwhelmingly as a noun. The verb form ('to outflow') exists but is rare and often sounds technical or awkward; 'flow out' is the more common verbal phrase.
The direct antonym is 'inflow', meaning the movement of something into a place or system. Other related opposites include 'intake' and 'influx'.
Rarely. It is typically neutral or negative, as it implies a loss or reduction of resources (money, people, liquid). In a neutral technical sense (e.g., 'lake outflow'), it simply describes a process.
An 'expense' is a cost incurred. An 'outflow' is the actual movement of cash out of the business. Not all outflows are expenses (e.g., loan repayments), and not all expenses immediately cause a cash outflow (e.g., depreciation). 'Outflow' is about cash movement; 'expense' is about accounting recognition of cost.
