Diogo is a ♂ male name.
Diogo is a Portuguese form of the name Diego, a Spanish variant of the Hebrew name James/Jakob.
Diogo means “may God protect” and “Saint James”, but as well “holder of the heel” (from Hebrew “‘akév/עָקֵב” = heel) or “supplanter” (from Hebrew “‘akáv/עָקַב” = to follow/to supplant), because he was born grasping the heel of his first born twin brother Esau and he bought his birthright to supplant him.
