Præposition

When I stated that ξυνήϊα was a compound word, and that the first part was the præposition ξὺν or σὺν, I should have added, that the latter seemed to me to be formed from ἐω or ἑω, to put or place, and that the word, so compounded, signified something put or placed together, probably contributions made by the people, in ancient times, to form a common stock.

In short, except in some compound words, where the præposition en comes before Σ, as ἐνσέιω, ἐνσημαίνω, the n is allmost universally dropped, and perhaps was here admitted to preserve a difference between the præposition and the augment.
