Into the valley of pronouns rode the, er, noble Mr Bamboo.
More pronouns (indefinites and interrogatives) in Unit 10, and u-, nt-, n- and s-stem adjectives. Actually, there were two types of u-stems, those with a nom and acc sg with a stem in –υ-, and the other cases in –ευ– ~ –ε(w)-, and those with a nom sg in –ευς. The loss of /w/ in Greek rather obscures the consonantal origins of the declension. s-stems are also similarly obscured because of the loss of intervocalic /s/ (aside: it survives in the sigmatic aorist by analogy). I don’t know whether s-stem adjectives only have the e-grade of the vowel in the stem formant (-εσ-) or there are some with the o-grade vowel (-οσ– as in neuter s-stem nouns).
ἐγὼ γάρ, ὦ ἄνδρες Ἀθηναῖοι, δι’ οὐδὲω ἄλλ’ ἢ διὰ σοφίαν τινὰ τοῦτο τὸ ὄνομα ἔχω. “For I have this reputation, men of Athens, because of nothing other than some wisdom.”
