Hear it in context
Notice where the phrase sounds natural.
Hold on, I'll check if he's in his office.
In my last job, I often had to ask customers to hold on while I looked up their information.
Fix the pattern
One small grammar move makes it sound right.
Not: Hold on the line, I'll get her.
Say: Hold on, I'll get her. / Hold the line, please.
Bare 'hold on' = wait; 'hold the line' is the phone-specific version (no 'on').
Which sounds natural?
Tap the one a native speaker would say.
'Hold on' is the natural spoken 'wait a sec'; 'please wait for a brief moment' is over-polite and stiff.
