Definitions for "Modularity"
A quality of a system where it consists of various parts which separate cleanly and fit together well. High modularity costs some design time but pays back well through clarity, elegance, maintainability and flexibility.
the design feature of being cleanly divisible into separate modules than can be moved, replaced, or adjusted more easily and independently than would otherwise be possible. Modularity is generally desirable, because it contributes to both program maintainability and data portability.

Java software to provide technology supporting template-driven Ant-based build systems, dependency analysis, IDE integration and much more for large projects composed of many modules/sub-projects.
The degree to which a system of programs is developed in relatively independent components, some of which may be eliminated if a reduced version of the program is acceptable.
Referring to an implant system where a specific component is made up of two or more detachable parts.

Those attributes of the software that provide a structure of highly independent modules. [McCall, Richards, and Walters, RADC, 1977
Many organisms consist of modules, both anatomically and in their metabolism. Anatomical modules are usually segments or organs. When we look at illustrations of metabolic reactions, we find that they, too, are modular: we can clearly identify, for instance, the citric acid cycle as a complex network that has only a few interfaces with other such modules.
A force design methodology that establishes a means to provide interchangeable, expandable, and tailorable force elements
Structure formed by modular, interchangeable building blocks
A framework that allows students the opportunity to gain a proportion of credit in modules that may not be directly associated with their named programme of study. These modules may be drawn from different Schools.
