Katniss and Peeta, along with the other tributes, go to the Training Center, where every district has a floor of its own. On floor 12, Katniss finds her room. It is large and plush and full of gadgets meant to make everyday jobs, like showering, picking out clothes, and preparing food, as easy as pushing a button. At dinner, Katniss, Peeta, Effie, and Haymitch are joined by Cinna and Portia, whose presence seems to make Haymitch and Effie behave a bit more politely toward one another. Katniss notes that this is the first time she has seen Haymitch sober; she tries some wine herself, but doesn't like the taste or how it turns her mind foggy.

Y would sound similar to a short E sound when said out loud. You wouldn't pronounce it yee-low, oh-low, or ollow (which is long e, long o, and short o respectively).
