likely to cause harm or injury
not safe and may cause harm or injury
Μοτίβο χρήσης:
[something] is unsafe to use
Συχνό λάθος:
Learners sometimes say *"not safe"* instead of using the single word *"unsafe"*. Both are correct, but *"unsafe"* is more natural in many collocations, such as *"unsafe working conditions"* or *"unsafe to drink"*. Another confusion is using *"insecure"* for physical danger; *"insecure"* usually describes emotional feelings or weak protection, while *"unsafe"* focuses on risk of harm.

|

Αντώνυμα
