Hello there,
Why couldn't I use "to doze off" instead of taking a nap? their meanings seem very smilar to me.

Thanks

Hi Selcuk, How are things in Instanbul? As for your question, to doze off means to fall asleep whereas to take a nap means to sleep for a while. Please mind that if you add the preposition off to the verb doze, you create a new verb with a new meaning.
More examples:
switch vs. switch off
take vs. take off
call vs. call off

I'm sure you can see the difference between both expressions now?
Let me know what you think,
Regards
Torsten

In this sentence is "drop off" = "nod off" = "to doze"?
