Words can be divided to subject and predicates, etc.
Predicates take any number of parameters (2 - 3 in spoken languages).
"Words can be divided to subject and predicates, etc. "
no, rather.....
"Sentences can be divided to subject and predicates, etc.
ie.
blue is color
yellow is color
You should realize that these statements are an abbreviation. What you really mean is:
"blue is an example of a color"
"yellow is an example of a color"
simply stating "blue is color" would mean that literally the word "color" can be subsituted for "blue". Which would mean you could convert:
"What color is your car?" , (if "blue is color" were true), then this would mean this question would be the same...
"What blue is your car?" dosn't make sense, thus "blue is color" is FALSE.
-------------------------
conclusion: predicate "is" relates subject color to subjects {blue, yellow}
FYI: "is" is the verb inside the predicate. The predicate is "is color" (or, should be "is an example of a color").
Also, "blue" and "yellow" are NOT subjects, they are the direct compliment nouns of the verb "is", (and "is blue" and "is yellow" are the complete predicate).
Sentence := subject + predicate, or, if you prefer
Sentence := subject + predicate.verb + predicate.direct-objects
there are many, many other possiblities though
Brainstorming further, predicate "is" mostly represents set->element or set->subset relation. Predicate "is" also represents syllogism. Other predicates mostly don't. Other predicates also can form a grouping of their's instances of particular parameter.
1. the word "is" by itself, tells you nothing really. Only by considering the associated information of the subject words and the direct compliment words can you infer what the 'is' means. That is, without considering any associated information that X has or that Y has, "(X) is (Y)" will get you no where. Also, don't ignore words like "the" and "a". Even the word "a" (indefinite article) can give vital clues. "(X) is a (Y)" means something quite different even than "(X) is the (Y)" or "(X) is (Y)". With "(X) is a (Y)" this suggests that (Y) is a named collection, of which (X) is one member, among others.
2. "their's" --->> "their" (don't need apostrohe s)
