What does modification mean?
A modification is a change made to something, especially a deliberate and usually limited adjustment to improve, correct, or adapt it. The word is common in formal and technical contexts involving documents, designs, products, systems, and plans. “Modification of” identifies what is being changed, while “make modifications to” describes the process. A modification may be as small as correcting a phrase in a contract or as substantial as altering a machine's design to meet new requirements. Compared with the broader word “change,” modification often emphasizes an adjustment made within an existing structure rather than a complete transformation. It can also refer to the general process of changing or adapting something, although that use is somewhat less common than the noun meaning an individual alteration.

Where does modification come from?
Modification entered English in the early 16th century from Latin modificatio, a noun formed from modificare, “to alter, moderate, or change.” The Latin verb was built from modus, meaning “measure, manner, or limit,” with the prefix modi- expressing measure or size. Its development preserved the sense of making a bounded adjustment: changing something by a particular measure rather than replacing it entirely. Related English forms include modify and modifier, while cognates in other languages reflect the same Latin heritage.
How modification is actually used
