In most cases if you have X and you make X-less, it means the same as “without X”. Example: -- Brain: Brainless = without a brain. I am brainless = I have no brain. -- Home: Homeless = without a home. I am homeless = I am without a home. But the two examples you give are exceptions to the rule because the meanings are special. -- Price: Priceless = with a price so high that you cannot put a number on it. A child’s life is priceless. My grandmother’s ring is priceless to me (I would never sell it and therefore never put a price on it because to me it has sentimental value). But if the ring is stolen by a thief, it is no longer priceless, because the thief has no sentimental attachment, and will take it to a pawn shop and sell it for whatever the diamonds are worth. -- Breath: Breathless = with a breath that I inhaled so fast because I’m so excited that I have no more breath left. I saw the Picasso and I was breathless. I inhaled my breath so fast, that I couldn’t inhale any more breath.

Hello Carlos, -"Less" as a suffix ( added to the end of a word) in your examples means without , destitute of, lacking, free of or simply not having . -It is substituted many times with the suffix "ful" to give exactly the opposite meaning of the adjective as for example : tasteful ,tasteless useful,useless etc

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!

Hi there, After a little though and searching I have come up with the following short explanation. "Less", as in priceless can be explained as having a value beyond. "Less", as in breathless or useless can be explained as not having or being able to obtain the value you're speaking of. I'm not sure that's enough of an explanation but maybe a good start. Good Luck!
