Kinship names by Marco Giannini
This infographic shows kinship names in 7 different European languages; three of them are neo-Latin languages, three are Germanic languages, and one is Slavic.
The terms are organized in circumferences: from the 'I' who observes his family around, to (part of) the fourth degree on the most external ring. There's also a broad, vertical organization according to the temporal sequence of the generations, from ancestors (above the 'I') to heirs (below). Same-generation relatives show approximately the same height.
Original root words (from Latin or Proto Germanic) lay near each node, whether they are known or reconstructed.
In the lower-left corner, the recurring affixes that mark the distance of a degree of relationship and kinship acquired are lined up in a table; finally, a small pie chart showing the percentage of consanguinity with the 'I' is added to each node.
