Change vs. Alter: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on January 12, 2024
Change refers to making something different, often fundamentally, while alter suggests modifying something without a drastic shift.

Key Differences

Change implies a fundamental difference in the form, nature, or appearance of something, often leading to a new form or structure. Alter, on the other hand, typically suggests a more subtle modification, adjusting or tweaking something without transforming its essence.
When we change something, it often becomes unrecognizable or significantly different from its original state. Alteration, in contrast, maintains the core identity of the subject but might modify certain aspects to suit different needs or contexts.
Change can refer to a wide range of transformations, from personal development to societal shifts. Alter, however, is usually used in contexts where the modifications are less extensive, such as altering a piece of clothing or slightly modifying a plan.
To change something can sometimes imply replacing it with something else, whereas to alter something suggests that the original item or idea is still present, but in a modified form.
Change is often used in a broader, more conceptual sense, encompassing a wide array of transformations. Alter tends to be more specific and is often used in technical or practical contexts, such as altering measurements or adjusting settings.
