A while ago I wrote a poem about time. But is in Dutch of course. Thanks to this forum I am able to write in English, but to translate a poem you need a lot more skill. I will start with the text in Dutch. Therefore you should know that timeless in Dutch is tijdloos. Tijd is time and loos is in fact very old Dutch and actually means "not what it seems to be". So a beautiful word to use in a poem.
Tijd
Tijd is loos,
vervliegt ontastbaar,
gedachten worden herinneringen,
die morgen vergeten zijn.
In English:
Time
Time is elusive,
evaporates intangible,
thoughts become memories,
that will be forgotten tomorrow.
You see, not the right nice words in English.
