Since you have come here looking for information, I shall reguerdon you with some.
reguerdon (n.) IPA Pronunciation: 
recompense, reward, repayment
KING HENRY VI
Stoop then and set your knee against my foot;
And, in reguerdon of that duty done,
I gird thee with the valiant sword of York
– Henry VI (III.i)
Also can used as a verb, exactly like the word reward. The word guerdon has the same meaning and uses as it does with the prefix re. The ability to drop or add a syllable and keep the same meaning is a useful tool to have to keep to the ten syllable meter of the verse.
