Grammar & Word origin
Sustentar is a transitive, regular -ar verb. Its present-tense forms include sustento, sustentas, and sustenta. It can also be used pronominally as sustentarse, commonly with en when expressing what something is based on.
It comes from Latin sustentāre, meaning “to hold up” or “to support,” related to sustinēre. Although the Latin root contains elements associated with “under” and “hold,” sustentar is not normally divided into meaningful parts in modern Spanish.
