Additional is another way to say “more than” or “further.” The word additional is an adjective, which means that it can be used to describe a noun or pronoun. Usually, you’ll see additional used to describe a noun.
In some instances, adjectives can be placed after the noun for emphasis. Here are two examples that use the word additional with different placement.
I have additional information on the report.
I have asked him about mattersadditional.
The first sentence tells you that there is extra information to be shared about the report; but, by placing the adjective before the noun, the information receives the emphasis.
The second sentence tells you that there are more matters to be discussed; but, by placing the adjective after the noun, the emphasis is put on the adjective, additional. In this sentence, additional is used as a postpositive adjective. Postpositive adjectives are used to give a poetic flair to the sentence.
Pronunciation of the word additional varies from British to American English. In the United States, the pronunciation draws out the first two letters, prolonging the word. The British pronunciation clips the “d” sound, making the word sound curt and precise.

When to Use the Abbreviation
As a general rule, abbreviations of any kind should be used sparingly. Even the common abbreviations for additional are not used in casual prose and are not prevalent. You’ll find them written mostly in reports, forms, and other texts that need to be summarized or shortened.
There are three standard abbreviations, and all feature the first three letters of the word.
Add. – This variation just uses the first three letters of the word, followed by a period.
Add’l. – This one uses the first three letters and the letter L with an apostrophe between the final D and L, followed by a period.
Addt’l. – This abbreviation has the closest resemblance in writing to the word additional, so it is the clearest of all three abbreviations.
Although the abbreviation addnl is sometimes used, it is not considered standard. Some style guides advocate for variations without apostrophes. Including the apostrophe can be helpful because it shows that certain letters have been omitted from the long word.
Rules to Remember
It is best to use abbreviations when you know your target audience will understand the abbreviated word in context.
Abbreviations for the word additional are not as popular or common in text as other abbreviations, like the Latin abbreviations for exempli gratia (e.g.), id est (i.e.), or et cetera (etc.). So, it may benefit your reader if you define the abbreviation and what it stands for. Write out the full word the first time you use it, and include the abbreviation in parentheses.
The abbreviation can be written with the first letter in upper case and the rest in lowercase when it begins a sentence. The abbreviation for additional adheres to the standard rules for capitalizing abbreviations.
Never use this abbreviation in the title of the text. Ensure the subject matter is clear for the audience.
