There are many words in English grammar of different and variant nature that help form unique and complex sentences. Some words also act as a link between sentences and help us convey our message in a series of sentences. Words like furthermore and moreover come under this category.
In a very general sense, we can understand these words as synonymous to words such as also, as well as, additionally, to add, etc. That means these are the type of words used in a sentence when we want to provide a list or additional information about something. Or else, these words can also be understood as the words that help link one sentence to another and provide a connection by discussing the first argument with further information.
As we can see, both words almost have the same meaning. They introduce further information. However, there can be a mild difference between the two.
Furthermore vs Moreover
Furthermore is the word that is used when we just want to add something to the list or give some additional information. The clause it represents does not necessarily require any argumentative link or connection to the previous clause.
- He is very punctual. Furthermore, he also cooks very well.
Moreover, on the other hand, is the word that not only adds something to the list but introduces added information that helps emphasize the previous argument of the first sentence.
- Drunk driving is very wrong. Moreover, it is dangerous.
So, this is the difference between the two. However, furthermore and moreover can be interchangeably used when it concerns only adding something to the list or providing added notes.
