_everything that_ (or _everything which_). The difference must be seen
by the meaning of the sentence, as _what_ hardly ever has an
antecedent.

The examples in sentences 5 and 6, Sec. 121, show that _who_ and
_which_ have no antecedent expressed, but mean _any one whom_, _either
one that_, etc.



OTHER WORDS USED AS RELATIVES.


[Sidenote: But _and_ as.]

124. Two words, but and as, are used with the force of relative
pronouns in some expressions; for example,--

1. There is not a leaf rotting on the highway _but_ has force in
it: how else could it rot?--CARLYLE.

2. This, amongst such other troubles _as_ most men meet with in
this life, has been my heaviest affliction.--DE QUINCEY.

[Sidenote: _Proof that they have the force of relatives._]

Compare with these the two following sentences:--

3. There is nothing _but_ is related to us, nothing _that_ does
_not_ interest us.--EMERSON.
