Combine synonym,synonyms of combine

Similarities: Both "merge" and "combine" imply bringing two or more things together to form a single entity or a unified whole. For example, two companies can merge/combine to form a larger one. In both cases, the individual elements lose their separate identities to some extent and become part of a new, integrated whole.
Differences: "Merge" often emphasizes the process of joining in a more seamless or fluid way. It's commonly used in contexts where the combination is relatively smooth and the boundaries between the original elements become less distinct. For example, we might say that two rivers merge, or that two ideas merge in a creative mind. "Combine" is a more general term and can be used in a wider variety of contexts, and the combination doesn't necessarily have to be as seamless. You can combine different ingredients in a recipe, where the individual components may still be somewhat distinguishable.

Similarities: "Unite" and "combine" both involve bringing things or people together. When people or groups unite or combine, they come together for a common purpose or to form a larger entity. For instance, countries can unite/combine forces to fight a common enemy.
Differences: "Unite" often has a stronger connotation of people or groups coming together in a more cohesive and collaborative way, usually with a shared goal or ideology. It implies a sense of unity and cooperation. "Combine" can be used more broadly for things as well as people, and the emphasis may be more on the act of putting things together rather than the strong sense of unity and purpose that "unite" implies. You can combine different materials to build something, but the materials don't have a sense of purpose or cooperation like people do when they unite.

Similarities: "Integrate" and "combine" both mean to bring different elements together to form a whole. When you integrate or combine different parts, you are creating a more complete and unified structure. For example, you can integrate/combine different software modules to create a more powerful application.
Differences: "Integrate" often implies a more systematic and organized way of bringing things together. It suggests that the different elements are being combined in a way that they work together seamlessly and function as an integrated whole. There is an emphasis on the compatibility and coordination of the parts. "Combine" is more general and can refer to simply putting things together without necessarily implying such a high level of organization and coordination. You can combine items in a random or less structured way, while integration usually implies a more planned and purposeful combination.

Similarities: "Blend" and "combine" both involve mixing or bringing things together. When you blend or combine different colors, flavors, or textures, you are creating a new combination that has characteristics of the original elements. For example, you can blend/combine different fruits to make a smoothie.
Differences: "Blend" often emphasizes the creation of a more homogeneous mixture where the individual elements are less distinguishable and have been thoroughly mixed together. It's commonly used in the context of things like blending colors, where the result is a smooth and even combination. "Combine" is more general and can refer to a wider range of ways of bringing things together. You can combine things in a way where the individual elements are still quite distinct, like combining different types of furniture in a room.

Similarities: "Fuse" and "combine" both mean to join or bring things together. When things are fused or combined, they are connected or joined in some way to form a single entity. For example, two pieces of metal can be fused/combined to make a stronger structure.
Differences: "Fuse" often implies a more permanent or irreversible joining, usually through the application of heat or some other process that causes the materials to bond at a physical or chemical level. It's commonly used in the context of materials or objects. "Combine" is a more general term and can refer to both temporary and permanent combinations, and it can be used for a wider variety of things, including ideas, concepts, and non-physical entities. You can combine ideas in a discussion, but you wouldn't say you fuse ideas in the same way you fuse metal.
