not able to be predicted
If something is unpredictable, you cannot know what will happen with it before it happens.
Padrão de uso:
an unpredictable [situation / event / result]
Erro comum:
Learners sometimes use *unpredictable* when they only mean *surprising*. *Unpredictable* suggests that you cannot reliably know in advance what will happen, not just that something is unusual. Another common error is misspelling it as *unpredictible*; the correct form is *unpredictable* with *-able*.
Sinónimos
uncertain (Focuses on not being sure about the result; slightly more formal and broad in use.)
|
erratic (Emphasizes irregular or uneven changes, often more negative in tone.)
|
volatile (Often used for markets, situations, or emotions that can change very quickly and strongly.)
Antónimos
predictable (The direct opposite: something can be known or guessed in advance without surprise.)
|
stable (Suggests not changing much over time, the opposite of frequent or surprising change.)
