Grupo vs. conjunto
While both grupo and conjunto can be translated as group in English, they carry different nuances. Grupo is the more general and common term, while conjunto often implies a more cohesive unit where the individual parts form a functional or aesthetic whole.
Grupo
A1Grupo is the most common and versatile word for group. It refers to any collection of people, animals, or things that are gathered together or share a common characteristic. It is used for both formal and informal gatherings and emphasizes the individual members that make up the collection.

Conjunto
A2Conjunto also means group, but it specifically describes a collection of items that are seen as a single, complete entity or set. The parts work together, belong together, or form a coherent whole. It is often used for outfits, musical ensembles, sets of objects, and in a more abstract sense, the whole.

Summary
In essence, use grupo as the general, default word for any collection of individuals or items (a group of friends, a work group). Use conjunto when you want to emphasize that the parts form a complete, functional, or aesthetically matched unit, such as an outfit of clothes (conjunto de roupa), a set of tools (conjunto de ferramentas), a housing complex (conjunto habitacional), or a musical ensemble. Conjunto highlights the whole, whereas grupo highlights the members.
