Using context clues and connotation helps us learn vocabulary. The use of context clues can help you learn definitions of words. You can do this by use of word association, or by seeing what words can replace the word. Connotation can also help you find out the definition of words. You can do this by using the way the word fits in and what it sounds like to associate it with another word or phrase.
A "flat character" is essentially a character who doesn't change throughout a story. They are seen as "stagnant" and remain the same, so it doesn't affect the storyline.
A chair I sat
with my head that thought
back to when good was the day
and fun was the night
these memories I ponder
sad it makes me
the past that is remembered
forgotten it’ll never be
