Other cases:
 
1st and 2nd person plural are straightforward, but in the singular ancient Greek has 2 forms:
  • one emphatic in speech and therefore accented in writing (to reflect this oral emphasis)
  • one neutral, unemphatic in speech and therefore unaccented and enclitic in writing.

Why do we use/not use the pronouns in the following?
  1. οἰκῶ ὲν τοῖς ἀγροῖς.
  2. ἐγὼ μὲν οἰκῶ ἐν τῇ Εὐρώπῃ, ὑμεῖς δὲ ἐν τῇ Ἀμερικῇ.
  3. σὺ δὲ ἄοκνος εἶ. Remember Dikaiopolis being energetic, not shirking work (in Greek: to work): οὐκ ὀκνεῖ πονεῖν)
  4. οἰκοῦμεν ἐν οἰκίαις, οὐκ οἰκοῦμεν ἐν ἄντροις. (caverns, at least most of us don't any more).
  5. οἱ κύονες ὑλακτοῦσιν, ἡμεῖς δὲ οὔ. (except very occasionally)
  6. ἐγὼ μὲν σε βλέπω, σὺ δὲ οὐ προσέχεις τὸν νοῦν. (you don't pay attention)
  7. σὲ μὲν ὁρῶ, αὐτὸν δὲ οὔ.
  8. ἡ μήτηρ οὐ σοῖ, ἀλλὰ ἐμοῖ νῦν γε παρέχει τὸ δεῖπνον, τί δὴ οὐχ ἥσυχος μένεις ὀλίγον χρόνον. δι' ὀλίγου μέλλει φέρειν τὸ δεῖπνον καὶ σοῖ.
  9. ὁ λαγὼς με ὁρᾷ καὶ φεύγει ἀπ' ἐμοῦ.
  10. συλλαμβάνομεν (βοηθοῦμεν) ὑμῖν.
  11. συλλάμβανε (βοήθει) ἡμῖν.
  12. ἡμεῖς μὲν συλλαμβάνομεν (βοηθοῦμεν) ὑμῖν, τί δὴ οὐ συλλαμβάνετε καὶ ἡμῖν ὑμεῖς;
  13. οἱ μὲν κύονες σῖτον λαμβάνουσιν ἀφ' ἡμῶν, φυλάττουσιν γὰρ οἴκους τε καὶ πρόβατα. (Why ἀφ' ?)
  14. δῶρα (gifts) ἀφ' ἡμῶν ὑμῖν, καὶ ἡμῖν ἀφ' ὑμῶν.
