therefore

[th air-fawr, -fohr] /ˈðɛərˌfɔr, -ˌfoʊr/
adverb
1.
in consequence of that; as a result; consequently:
I think; therefore I am.
Origin
1125-1175
1125-75; Middle English ther(e)fore, variant of therfor therefor
Can be confused
therefor, therefore (see synonym study at the current entry)
Synonyms
hence, whence. Therefore, wherefore, accordingly, consequently, so, then all introduce a statement resulting from, or caused by, what immediately precedes. Therefore (for this or that reason) and wherefore (for which reason) imply exactness of reasoning; they are especially used in logic, law, mathematics, etc., and in a formal style of speaking or writing. Accordingly (in conformity with the preceding) and consequently (as a result, or sequence, or effect of the preceding), although also somewhat formal, occur mainly in less technical contexts. So (because the preceding is true or this being the case) and then (since the preceding is true) are informal or conversational in tone.
