from The Century Dictionary and Cyclopedia
- That is now present or at hand: a demonstrative adjective used to point out with particularity a person or thing that is present in place or in thought.
- Time just past or just at hand; the last or the next. The reference, whether to past or to future, is determined by the circumstances; this evening may mean either the evening now approaching, or next to come, or the evening now present, or the evening just past: as, it has occurred twice this year; I shall take care not to fail this (next) time. In this connection this is sometimes used for these, the sum being reckoned up, as it were, in a total.
- This person or thing.
- Something that has just preceded or has been mentioned or referred to.
- Emphatically, something that is to be immediately said or done: as, Let me tell you this: I shall lend you no more money.
- Elliptically, this person, place, state, time, position, circumstance, or the like: as, I shall leave this [place or town] to-morrow; this [state of affairs] is very sad; I shall abstain from wine from this [time] on; by this [time] we had arrived at the house.
- When opposed to that, this refers to the person or thing that is nearer, that to the person or thing that is more distant; so, with things that have just been expressed, this refers to the thing last mentioned (and therefore nearer in time to the speaker), and that to the thing first mentioned (as being more remote).
- For this; thus.
