A word loved by poets in five equal parts
The end of a dog is how two of them start
The third can be found in the land of Jafar
The fourth can be useful to learn where you are
The fifth is a word that an anchor might use
Announcing the start of tonight's evening news
Note: A complete answer should explain all of the clues.
Edit: I just noticed that I made a slight error in how this is spelled, in that one of the parts is slightly larger than the other 4. I'm not sure if I can explain this in the verse and still make it rhyme, so I'm just gonna leave this here.
Just double one of the letters. It does not affect the pronunciation.
It's been a little while, so here's another hint:
Note that "dog" and "anchor" are singular. This is significant. In retrospect "poets" should probably be singular be as well.
