Key Differences
Fill involves making something full by adding a substance or occupying space within it. For example, you can fill a glass with water, meaning you pour water into the glass until it is full. Fill can also refer to occupying time, as in filling a schedule with activities. Fit, on the other hand, refers to being the correct size or shape for a specific space or purpose. For instance, clothes that fit well are the right size for the person wearing them. Fit can also imply suitability, such as a candidate being a good fit for a job.
Fill is often used in contexts where something is being added to reach capacity, such as filling a container, room, or gap. Fit is used when discussing the appropriateness of size, shape, or compatibility, such as fitting into clothes, a role, or a particular space.
Fill typically involves a process of adding or occupying, whereas fit involves matching or being compatible. Fill can be both a verb and a noun, while fit is mainly a verb and can also be used as an adjective.
Fill might imply completion, as in filling out a form completely. Fit implies correctness and harmony, ensuring that something is suitable or appropriate.
