Interrogatives and Indefinites
pages79 (108/9) and 225/6 (297)

Interrogatives are always stressed on the first syllable. And their stress is always acute
τίς ἔρχεται ; 
- ὁ βασιλεύς 
τίνων ναῦς ἀφικνεῖται εἰς τὴν Κρήτην ;
- ἡ τῶν Ἀθηναίων ναῦς 
τίνι πείθονται οἱ ἑταῖροι; 
- τῷ Ὀδυσσεῖ 

Indefinites are enclitics (lean on their stronger preceding neighbours). They can only be stressed on the last syllable when they follow an acute penult

προσχωρεῖ ἀνθρώπῳ τινὶ καὶ λέγει· χαῖρε.... 
He goes up to some man and says: Hi there....
ἕπονται παρθένοις τισί, θαυμάζουσιν γὰρ αὐτάς. 
They follow some girls because they admire them, their beauty.
(θαυμάζουσιν τὸ κάλλος αὐτῶν.)
ὁρῶσι οἶκόν τινα καὶ τύπτουσι τὰς πύλας 
They see a (certain) house and knock on the gates
(maybe they've lost their way, or are thirsty, or want to ....)
