sothat

Sothat is not a standard English word. In ordinary writing, the correct form is the two-word conjunction so that, which introduces a purpose or a result clause. The term sothat may appear as a typographical variant, a string in a computer filename, or a proper noun in a domain-specific context, but it has no common, recognized meaning on its own in standard grammar.

Usage and meaning

So that introduces a clause that explains the purpose of an action or the consequence that follows from it. It is used to show intention, goal, or a future outcome. Examples: She saved money so that she could buy a new bike. The door was left open so that the room would stay cool. So that can also express potential or ability when combined with a modal verb: He whispered so that he could not be heard by others.

Grammatical notes

The clause that follows so that is usually finite, with its own subject. The tense of the result clause can reflect the time of the main clause, and the mood may include can, could, may, or would depending on meaning. So that is often contrasted with in order that, which tends to be more formal, and with so as to, which is typically followed by the base form of a verb and lacks a subject in the clause that follows. Avoid using so that to express purpose with an infinitive without a subject; use so that to introduce a full clause instead.
