The Definite Demonstratives are very frequently used to point out the Noun which stands as Antecedent to some Relative Pronoun following.
1. This man whom you see here arrived only this morning.
2. That book which you are reading is mine.
3. He is not such a clever student as you are.
4. You are reading the same book that I read many years ago.
SOME & ANY
It depends upon the sense whether these are Demonstrative Adjectives, Adjectives of Quantity or Adjectives of Number.
(1) Some man called here today. (Indefinite Demonstrative Adjective)
(2) Give me some bread. (Indefinite Quantitative Adjective)
(3) Give me some loaves of bread. (Indefinite Numeral Adjective)
(1) Take any book that you like. (Indefinite Demonstrative Adjective)
(2) He has not had any bread. (Indefinite Quantitative Adjective)
(3) Did you bring any loaves? (Indefinite Numeral Adjective)
Both of these Adjectives are Indefinite. But, as may be seen from the following examples, SOME is the less Indefinite of the two.
1. Would any man take money from the poor? Yes, some men would.
2. Take any books that you like. But you must take some.
3. Can you come some time today? Yes, at any time you like.
In a question SOME often anticipates or hopes for an affirmative answer where ANY leaves the question open.
1. Have you some eggs you could sell me? (=I hope you have).
2. Have you any eggs you could sell me? (= you may or may not have.)
