Which is the proper way to use this sentence: People have crazy views and idea(l)s about what love is suppose(d) to be.
People have crazy views and ideas about what love is supposed to be.
You could also use it as a bottle opener. It’d work, though some upper crusters might protest that it’s not proper.
Not sure I understand that one. Enlighten me.
I think the OP goes wrong where it says ‘use this sentence’ where it seems to be looking for ‘what is grammatical and/or reflects the correct usage’. The proper way to ‘use’ this sentence is to use it in a context where the meaning of the words reflects what you want to say or write. For instance, in a discussion about love, in which you want to contend that people have crazy ideas or ideals (either is possible, I guess) about what love is supposed (here you have to go with the past participle of ‘to suppose’; ‘what love is *suppose to be’ is wrong) to be.
Agreed.
Ditto. One could follow that sentence with “I suppose they have high ideals that are never met.”
