relative clause (with it) being equivalent to a pure noun, the conjunction clause to a verbal noun in apposition, partly retaining its verbal character. In both, also, the predication answers an imaginary question, recorded distinctly in the relative, less distinctly in the conjunction clause. 'What do you want?' 'It (the thing) that I want is money.' 'To whom did you give it?' 'It (the persons) that I gave it to was your friends.' 'As to your cutting it: give particulars.' 'It—that I cut it (my cutting it)—was with a knife.'
From the above examples it will be seen that the two constructions largely overlap. When (as in 1,2, 5, 8) the relative is subject or direct object of the clause-verb, or is in the possessive case, it cannot be replaced by the conjunction; but when its relation to the clause-verb is marked by a preposition, the conjunction always may take its place, and sometimes must, as in 12 and 13. For the relative clause can only be used when the question reflected in it is calculated to secure the right kind of answer. Now the natural answer to the question 'What did you cut it with?' is not 'difficulty' but 'a knife'. The misleading 'with' is therefore removed from the relative clause in 13, and placed within the predicate, the definite question 'What did you cut it with?' giving place to the vague demand for particulars. 'With' being removed, the relative clause falls to pieces, for want of a word to govern the relative, and the conjunction clause takes its place. In the same way, 'it was a cab (but not high indignation) that he drove away in'; 'it was a concert (but not curiosity) that I was returning from'; 'it was a beech-tree (but not unpleasant circumstances) that I found him under'. And, generally, it will be found that a preposition is admissible in the relative clause only when used in the literal or the most obvious sense.
The conjunction clause is, as we have said, a verbal noun; so far a noun that things can be predicated of it, and so far a verb that the things predicated of it are verbal relations and
