What does modifiable mean?
“Modifiable” means capable of being changed, altered, or adjusted rather than remaining fixed in one form. It is a precise and slightly formal adjective, especially useful in scientific, technical, legal, and organizational writing. A modifiable variable can receive a new value, a modifiable property can be edited, and a modifiable procedure can be revised without being replaced entirely. The word does not necessarily imply that change is easy or desirable; it simply identifies something as open to alteration. This distinguishes it from terms such as “mutable,” which can suggest susceptibility to change, and “adjustable,” which often emphasizes fine-tuning. Although “modifiable” may sound overly formal in casual conversation, it is valuable when precision matters. Saying that a rule is modifiable clearly identifies the rule as changeable, while indicating that its present wording is not fixed beyond revision.

Where does modifiable come from?
The English adjective belongs to the word family of “modify” and “modification,” all of which derive from Latin modificare, meaning to alter, limit, or modify. Latin modificare was formed from modus, meaning measure, manner, or limit, and facere, meaning to make.
