IPA: /nɒnspɪsɪfɪkli/
KK: /nɑnspɪsɪfɪkli/
In a way that does not refer to a specific thing or detail.
The symptoms were described nonspecifically, making it hard to diagnose the illness.
Nonspecifically → It is formed from "non-" (meaning not) and "specific" (from Latin "specificus", meaning particular or distinct) and the suffix "-ally" (meaning in a manner). The word "nonspecifically" means in a manner that is not particular or distinct.
Think of 'not' ('non-') being combined with 'specific' to remember that 'nonspecifically' means in a way that is not particular.
