In modern English, grave is not normally used as a verb, but can be a noun, a noun adjunct (grave marker), or an adjective meaning serious.
The transitive verb grave is identical to engrave. But this is nearly an archaic usage. It has an old nautical use meaning to clean and coat a wooden hull with pitch.
Examples:
"It takes time to grave (engrave) a tombstone."
"In the drydock, the workers began to grave the keel of the old French ship."
"Is" is the verb. It's a linking verb that connects the subject--Zia Concetta--to the additional information about the subject--the oldest person in Barletta.
It is a verb form, ending in -ing. But it is used as a noun.
A gerund is a verb form that functions as a noun in a sentence. It is formed by adding "ing" to the base form of a verb, and can be the subject or object of a sentence, or be used in other noun positions. For example, in the sentence "Swimming is her favorite hobby," "swimming" is a gerund.
is(Mrs. Parks is the subject. Is is the verb, the simple predicate. Is 83 years old is the verb phrase, the complete predicate)
A gerund or gerund phrase functions as a noun, as the subject of a sentence or a clause, and as the object of a verb or a preposition. Examples:Fishing is my dad's hobby. (subject of the sentence)I need the workout that swimming provides. (subject of the relative clause)We enjoyed the dancing in the parade. (direct object of the verb 'enjoyed')He'll need new shoes for running. (object of the preposition 'for')
