"Form of Treasure"
The name Trezure is commonly a female name from the "English" origin.
Trezure is a respelling of Treasure, the English vocabulary word used as a given name. The spelling replaces the s with z and drops the a, so the written form matches the usual pronunciation of the word. It first appears in United States birth records in 1995, which fits a late twentieth century respelling rather than an inherited name.
Treasure means "Precious".
The pronunciation of Trezure is TREH-zhur.
