...nothing in them but tittering jeering emptiness. - William Butler Yeats

Words are always getting conventionalized to some secondary meaning. It is one of the works of poetry to take the truants in custody and bring them back to their right senses. Poets are the policemen of language; they are always arresting those old reprobates the words.

Though I am old with wandering
Through hollow lands and hilly lands,
I will find out where she has gone,
And kiss her lips and take her hands;
And walk among long dappled grass,
And pluck till time and times are done
The silver apples of the moon,
The golden apples of the sun.

- The Song of Wandering Aengus

I went out to the hazel wood
because a fire was in my head
cut and peeled a hazel wand
and hooked a berry to a thread
and when white moths were on the wing
and moth-like stars were flickering out
I dropped the berry in a stream,
and caught a little silver trout....

(Song of Wandering Aengus)
