T'hy'la in Greek = WTF??

Caught a re-run of Troy on TV and watched a bit (before this damn, fucking digital tv thing got pixeling and everything). So, having spotted a couple of two of interesting quotes, and many minutes later after having - by chance - found a transcript, I've decide it was worth to search more about Patroclus funeral.

And here's the thing. From Wikipedia's page about Achilles and Patroclus.

For Achilles ... in his own ascending scale of affection as dramatized by the entire composition of the Iliad, the highest place must belong to Patroklos.... In fact Patroklos is for Achilles the πολὺ φίλτατος ... ἑταῖρος — the ‘hetaîros who is the most phílos by far’ (XVII 411, 655).^[1] 

Hetaîros meant companion or comrade; in Homer it is usually used of soldiers under the same commander. While its feminine form (hetaîra) would be used for courtesans, an hetaîros was still a form of soldier in Hellenistic and Byzantine times. In ancient texts, philos denoted a general type of love, used for love between family, between friends, a desire or enjoyment of an activity, as well as between lovers.

So...
...
Philos = the affection between t'hy'lara?


Just... WTF??
