Grammar fix
a grey area
an unclear or undefined situation
a situation, rule, or topic that is not clearly defined and where it is difficult to say what is right or wrong, or what should be done.
Hear it in context
Notice where the phrase sounds natural.
The law on using drones is still a grey area, so people aren’t always sure what’s allowed.
There are many grey areas when it comes to privacy online, as technology is changing faster than the laws can keep up.
Fix the pattern
One small grammar move makes it sound right.
Not: It's a grey zone legally.
Say: It's a grey area legally.
The fixed phrase is 'grey area' (BrE) / 'gray area' (AmE), not 'grey zone'.
Which sounds natural?
Tap the one a native speaker would say.
'Grey area' is the everyday way to flag 'unclear/undefined'; the paraphrase is legalese.
