Jarrett is an uncommon yet distinctive given name of American origin. It is derived from the Old French name Gerart, which was itself a variant of Gerald. The name Gerald evolved from the Germanic elements 'ger', meaning 'spear', and 'wald', meaning 'rule'. Therefore, Jarrett can be interpreted to mean 'rules with the spear', suggesting a historic or warrior lineage. In its contemporary usage, Jarrett is often associated with individuals born in the latter half of the 20th century, as it gained popularity during this period.
"The name Jarrett experienced a peak of popularity between 1983 and 1986 with consistent birth counts of six or more each year, reaching its highest point in 1984 with eleven births. The name's popularity began to decline after 1999, with only five births recorded in 2000 and 2002."
