INTERROGATIVE PRONOUNS.

[Sidenote: _Three now in use._]

97. The interrogative pronouns now in use are _who_ (with the forms
_whose_ and _whom_), _which_, and _what_.

[Sidenote: _One obsolete._]

There is an old word, _whether_, used formerly to mean which of two,
but now obsolete. Examples from the Bible:--

_Whether_ of them twain did the will of his father?

_Whether_ is greater, the gold, or the temple?

From Steele (eighteenth century):--

It may be a question _whether_ of these unfortunate persons had
the greater soul.

[Sidenote: _Use of_ who _and its forms._]

98. The use of _who_, with its possessive and objective, is seen in
these sentences:--

_Who_ is she in bloody coronation robes from Rheims?--DE QUINCEY.

_Whose_ was that gentle voice, that, whispering sweet,
Promised, methought, long days of bliss sincere?--BOWLES.

What doth she look on? _Whom_ doth she behold?--WORDSWORTH.

From these sentences it will be seen that interrogative _who_ refers
to _persons only_; that it is not inflected for gender or number, but
for case alone, having three forms; it is always third person, as it
always asks _about_ somebody.

[Sidenote: _Use of_ which.]

99. Examples of the use of interrogative _which_:--

_Which_ of these had speed enough to sweep between the question
and the answer, and divide the one from the other?--DE QUINCEY.

_Which_ of you, shall we say, doth love us most?--SHAKESPEARE.

_Which_ of them [the sisters] shall I take?--_Id._

As shown here, _which_ is not inflected for gender, number, or case;
it refers to either persons or things; it is selective, that is, picks
out one or more from a number of known persons or objects.

[Sidenote: _Use of_ what.]

100. Sentences showing the use of interrogative _what_:--
