This is Beautiful:

Had I the heavens' embroidered cloths,
Enwrought with golden and silver
light,
The blue and the dim and the dark cloths
Of night and light
and
the half-light,
I would spread the cloths under your feet:
But
I, being
poor, have only my dreams;
I have spread my dreams under your
feet;
Tread softly because you tread upon my dreams. -W.B
Yeats

This is Pretty:

I've been living with a shadow overhead
I've been sleeping with a cloud
above my bed
I've been lonely for so long
Trapped in the past, I just
can't seem to move on

I've been hiding all my hopes and dreams away
Just in case I ever need `em again someday
I've been setting aside time
To clear a little space in the corners of my mind
-Way back
into love

Pretty:

On the stretch of road between school and my bus stop, Vanessa and I somehow got into a conversation about pretty people in class.(names shall not be mentioned in the case of an inflated ego)

No idea why she asked but "What is your definition of pretty because sometimes your "pretty" is like...." -makes a, your sanity is definitely questionable face-

I don't have an answer to that actually, pretty is as pretty does. What reason can i give for something to be pretty?I think some flowers are pretty like a daffodil, some words are pretty too.

Ebullient,effervescent,catalyst.

Pretty words.

I guess i can draw a conclusion and say i associate pretty with really girly qualities. For example, alphabets for me have a gender.

A is a girl(because an apple is a really pretty fruit).
B is a boy(B for boy)
C is a girl(Cats are felines).

E is some sort of gender bender because it can appear really feminine or as a really immaculate boy.

I like the letter E. Its quite exquisite.

Some buttons are pretty. Glitter is pretty. Frills and lace are pretty.

How do i put this in words?

Words like pretty, beautiful , ugly just encompass too much that i don't even want to define them.

They should just get visual aids.
