Usage tips
Context clue
To distinguish the two meanings, pay attention to the context. If it is about architecture, buildings, or art, it means the roof vault. If it is about politics, power, or organizations, it means the leadership group.
EXAMPLE

The dome of the mosque is decorated with mosaics.
Typical collocations
In the architectural sense, 'Kuppel' (dome) is often combined with adjectives such as 'gläsern' (glass), 'golden' (golden), or 'gewaltig' (huge). It also frequently appears in the genitive to show belonging, e.g. 'die Kuppel des Doms' (the dome of the cathedral).
EXAMPLE
Die gläserne Kuppel des Gebäudes bietet einen Panoramablick über die Stadt.
The glass dome of the building offers a panoramic view over the city.

The figurative meaning for a leadership group is used mainly in journalistic or political texts. It can have a slightly critical or detached undertone.

Kuppel vs Spitze
tip / top / lace
'die Spitze' and 'die Kuppel' can both figuratively mean a leading group. 'die Spitze' is the normal word for the highest position or leadership, for example in a company, party, or ranking. 'die Kuppel' more often means a small circle of powerful people in an organization or in politics, and it often sounds more critical. The words can be confused because both point to people at the very top. In neutral situations, 'Spitze' is usually more natural; 'Kuppel' fits better when you want to emphasize power within a tight circle.
