Can you reborn a ritual monster in yu gi oh trading card game from the graveyard?

only if the monster has been summoned to the field, and the summon was not negated.

also, if the card says 'this can only be -insert summon type- summoned by -insert ritual/Special summon info-

ritual summon only (this card can only be ritual summoned by) -Only ritual summon

Special summon only(This card can only be Special summoned by) -Only special summon,

hope this helps.
