Teri, ah yes, I see you haven't posted anything yet! It's hard to give advice because I capture words and make them a hook (which I usually put in the chorus or make it the last line of every verse in a song that will not have a chorus.) I have so many one liners in my phone memo section that if Shane McAnally called me and said do you want to co-write? I'd say yea, I've got a hundred hooks, which one do you want!? LOL.
So I suggest to pick your genre of music.
Then look up the lyrics of your favorite songs and look for the pattern:
of how many lines in a verse,
what is the rhyme scheme,
how many verses,
where does the chorus fall into place
and is there a bridge?
You can base your structure on what's being done. This is good because your audience will be familiar with the structure and be drawn to your song more easily.
Usually my chorus will have a different count of lines than the verses and always a different rhyme scheme. I tend to repeat the hook (which generally adds two more lines) It's ok to not start with the chorus when writing. This actually will give you an edge if you co-write with someone who writes the chorus first. Co-writing might be a great way for you to get your feet wet, because the chorus is historically the answer to the verses, so it'd be easy for you!
Once you get the basics down, you can start creating your own way of writing so you don't become one of those "cookie cutter writers" that write the same stuff over and over and over again!
I've got tons more advice! BUT I've got tons more to learn so I'm not trying to be snarky at you LOL.
