Examples
By Part of Speech
verb

Learning
Memory Aids
Mnemonic
Think of 'IN' (not) + 'DETERMINE' (to fix or decide) + 'ACY' (state of) = the state of not being able to be fixed or decided.
Conceptual Metaphor

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'индетерминация' unless in a very specific academic/philosophical context. 'Неопределённость' is the standard equivalent for most uses.
- Do not confuse with 'indecision' (нерешительность), which is a personal psychological state.
Common Mistakes
- Misspelling as 'indetermancy' or 'indeterminance'.
- Using it to mean simple 'indecision' rather than a state of inherent uncertainty.

FAQ
Frequently Asked Questions
Not exactly. Ambiguity often implies multiple possible meanings, while indeterminacy implies a fundamental lack of a single determinable fact or outcome. Indeterminacy is more about the impossibility of precision.
It would sound very formal and out of place. Words like 'uncertainty' or 'vagueness' are far more common in general conversation.
It's Heisenberg's Uncertainty Principle, which states that certain pairs of physical properties (like position and momentum) cannot both be known exactly at the same time.
The primary adjective is 'indeterminate'. 'Indeterminable' is also related but means 'not able to be determined or ascertained'.
