The nom. masc. sē, and the nom. fem. seó are from a different root. AS. ðaet is akin to D. dat, G. das, OHG. daz, Sw. & Dan. det, Icel. þat (masc. sā, fem. sō), Goth. þata (masc. sa, fem. sō), Gr. (masc., fem.), Skr. tat (for tad, masc. sas, fem. sā); cf. L. istud that. √184. Cf. The, Their, They, Them, This, Than, Since.]

1. As a demonstrative pronoun (pl. Those), that usually points out, or refers to, a person or thing previously mentioned, or supposed to be understood. That, as a demonstrative, may precede the noun to which it refers; as, that which he has said is true; those in the basket are good apples.

☞ That is often used in opposition to this, or by way of distinction, and in such cases this, like the Latin hic and French ceci, generally refers to that which is nearer, and that, like Latin ille and French cela, to that which is more remote. When they refer to foreign words or phrases, this generally refers to the latter, and that to the former.

Two principles in human nature reign;
Self-love, to urge, and Reason, to restrain;
Nor this a good, nor that a bad we call. Pope.

A judgment that is equal and impartial must incline to the greater probabilities. Bp. Wilkins.

☞ If the relative clause simply conveys an additional idea, and is not properly explanatory or restrictive, who or which (rarely that) is employed; as, the king that (or who) rules well is generally popular; Victoria, who (not that) rules well, enjoys the confidence of her subjects. Ambiguity may in some cases be avoided in the use of that (which is restrictive) instead of who or which, likely to be understood in a coordinating sense. Bain. That was formerly used for that which, as what is now; but such use is now archaic.

We speak that we do know, and testify that we have seen. John iii. 11.

That now on Monday last I saw him wirche [work]. Chaucer.

Formerly, that was used, where we now commonly use which, as a relative pronoun with the demonstrative pronoun that as its antecedent.

And childish error, that they are afraid. Shak.

(d) To introduce a consequence, result, or effect; – usually preceded by so or such, sometimes by that.
