I think the word you have in mind is "utilitas" which means "utility" or "usefulness". It's sort of hard to tell how to approach a word unless you know the context, because it can be an invented word, an error, an unusual word, or simply a word that isn't in the dictionary for some reason.<br /><br />The word utilitas comes from the word utilis/utile which means "useful" or "helpful". The word utilis/utile itself comes from the verb utor, uti, usus sum meaning "to use", whence we derive the English word "use" among many others.<br /><br />Some uses of utilitas from Cassel's Latin Dictionary are:<br />utilitas parta per amicum<br /> -Cicero, Pliny, Horace<br />"an advantage/benefit gained through a friend"<br /><br />utilitates ex amicitia maxime capientur<br /> -Cicero<br />"profits will be most especially taken out of friendship"<br /><br />As you can see, words, just as in English, can take on any number of meanings, and even more when put into these special statements. Maybe you can clarify where you found the word?
