In our discussions around the theme of solid fluids, we often resort to everyday words, many of them of ancient derivation and rich in association. We have decided to make a list of some of the words that come up most often - barring those that already figure as the principal characters of individual contributions - and to distribute among ourselves the task of writing a sort of mini-biography for each. The resulting lexicon with 19 entries, ranging from 'cloud' and 'concrete' to 'wave' and 'wood', serves as a conclusion to the collection as a whole.
