Hydroponics Are My Future

Destined is love to cost
Thy those dearest,

If you're trying to say "Destined to cost you those dearest," but want to use the archaic form of "you", the correct version is "thee": "Destined to cost thee those dearest,"

Not sure you should though. If it's something you use in everyday speech, fine, but if you're using it to try to sound "poetic", I would advise against it.
