The key difference between thereby and therefore is that thereby means “by that means” or “as a result of that” whereas therefore means “for that reason” or consequently.
Both thereby and therefore are adverbs we use as transition words. Although look and sound somewhat similar, there is a distinct difference between thereby and therefore in terms of meaning as well as usage. Thereby generally indicates the subsequent result of the clause that precedes it whereas therefore indicates the reason why something happened or was done as a result of the clause that precedes it. Furthermore, when compared to therefore, thereby is more formal and less common, especially in conversations.

What Does Thereby Mean?
Thereby is an adverb with the meaning ‘by that means’ or ‘as a result of that’. We use this adverb to announce an important result or consequence of the event or action you have just mentioned. For example, let’s look at the sentence, “Ryan studied for two straight weeks and was thereby able to get the top score.” This indicates that Ryan obtained the top score through the action of studying. Hence, this adverb basically means by which or through which action, something happened.
