Furthermore, as sentence adverbs, "further" and "furthermore" are frequently used at the beginning of sentences (followed by a comma). Rather, it is used as an intensifier. Thus, "further" followed by a noun or a verb is an adverbial phrase that modifies the meaning of the following word.
Adverbs alter and characterize verbs and adjectives. When this occurs, these adverbs are frequently placed at the start of sentences or phrases. These are known as introduction adverbs. When we employ introductory adverbs to alter a sentence, we must follow the adverb with a comma. In the following example, I have inserted commas after each introductory adverb: He enthusiastically, quickly, and quietly left.
Introductory words, like introductory sentences, must be separated by a comma. We employ a comma after introductory words to distinguish the introduction word from the independent sentence. Here's a hint: Commas might be perplexing, but they don't have to be. Adverbs are usually used as the first word in a phrase. Introductory adverbs are words like obviously, clearly, and naturally that give away the fact that they're important words in the sentence.
After transition words and phrases that begin a sentence, use a comma: although, thus, on the other hand, for example, and so on. In the midst of a sentence, use a pair of commas to separate transition words and phrases, as well as clauses that are not vital to the sentence's content. For example, if you were writing about the dangers of smoking, you would place a comma before "there," since it is used to signal that what follows is a new thought.
The comma is normally omitted when an initial prepositional phrase is relatively short (less than four words). If the sentence is more than four words lengthy, use a comma. When your introduction sentence comprises two prepositional phrases, a comma is preferable. This helps the reader understand that he is not being given a single idea but two separate ideas.
A prepositional phrase is a group of words that functions as part of a larger sentence structure to indicate where something is, who or what it is, or how it is done. For example, in "The book was written by John, James, and Peter," written is the prepositional phrase that modifies book. There are several other examples of prepositional phrases in this sentence: by, from, for, and to. Commas are used to separate these prepositional phrases from each other and from the rest of the sentence.
Prepositions are words like by, from, for, with, without, to, too that show relationship between two objects or actions. They can be divided into five groups based on usage: positional, relative, possessive, conjunctive, and demonstrative. Positional prepositions like near, next to, under, above, behind, and beyond show relationship between one object and a location.
To separate an introduction from the main portion of the phrase, use a comma. [Full sentence], [coordinating conjunction], [Full sentence]. Use a comma to separate two full phrases that are connected by a coordinating conjunction. There are seven coordinating conjunctions: and, but, or, nor, yet, so, and for. Using these words in conjunction with commas will help readers understand the relationship between the parts of your sentence.
Elements of the Beginning
Place a comma before the conjunction and, or, but, nor, still, so, or for when joining two full sentences. If you just use a comma, you will produce a comma splice, which will make your pals giggle.
