It is very common to be greeted with a question about being 'fine'. For example, "are you fine" today? How are you? Are you alright? Are you okay? These example questions all ask about being fine.
The clear distinction is to use 'fine' to mean being in either a temporary satisfactory state or a permanently good state. As 'to be' is a verb which truly always links the subject to complementary information it doesn't describe doing an action in a certain way. 'To be' sometimes seems to be referring to a permanent state as with an adjective being connected to the subject. For example, you are a 'fine' person.
So how often does 'alright', 'okay' and 'fine' refer to an 'alright', 'okay' and 'fine' person during greetings?
