Hey there! When we use sum as an adjective, we are usually talking about the total or complete amount of something. Think of it as a way to say, 'this is everything combined.'
You will often see it used in phrases like sum total. It serves to emphasize that no parts were left out. It is a very precise word that adds a sense of finality to a calculation or a collection of items.
The word sum comes to us from the Old French word summe, which traces back to the Latin summa, meaning 'top' or 'highest part'. It is quite fascinating because it implies that the total is the 'peak' of all individual numbers added together.
Historically, it has been used in mathematics for centuries. Over time, it moved from being just a noun for a math result to an adjective used to describe the completeness of a situation or a collection.
In English, you will mostly see sum used as a noun, but as an adjective, it is quite specific. It is almost always found in the collocation sum total.
This usage is typically formal. You would use it in a business report or a math textbook rather than during a casual chat with friends. It adds weight and authority to your description of a final figure.

As an adjective, sum is invariable, meaning it does not change form. It is pronounced /sʌm/ in both British and American English, rhyming with hum, drum, and mum.
It is usually placed before the noun it modifies, such as in 'the sum total'. Because it is a short, single-syllable word, it carries strong stress when spoken, making it sound definitive.
