hey carlos! :) well the way i see it is without literally meaining- not with "its hard for me to live without food" :P a common phrase is "i can't live without u" so u can describe "without" to people as something that u do not have another example-"she was without fault" if u say that something is priceless, it is something that cannot be bought- usually something special to someone a smile is priceless, joy is priceless as in it cannot not be attained by money it does not have a price. now for breathless- it also means not having breath it is a exaggeration commonly used to describe how one is feeling. "the wonderful memories that were rushing through his mind left him laying there breathless" it usually is thought of as a positive word. but the majority of other words that have the word "less" in them like "hopeless"(not having hope), carry a negative association. and hopefully this will be helpful 2 u adios!
