To paraphrase Abraham Lincoln, notarizations aren't always all one thing or all the other. Sometimes a notarization is both an acknowledgment and a jurat. And that's called a hybrid certificate. In this case, the notarial certificate may combine both acknowledgment and jurat wording, meaning the signer must both acknowledge a signature and be administered an oath by the Notary. For example, your signer might be a partner in a business who is signing a contract on behalf of the partnership. His signature would need to be acknowledged and he also would have to execute a sworn or affirmed statement that he is a partner in the business. In this case, the notarial certificate may include the phrases 'acknowledged before me' and 'subscribed and sworn to.' In your journal you can describe a hybrid as an 'acknowledgment/jurat'or 'acknowledgment with oath,' or something similar. California Notaries cannot complete this type of hybrid wording, but, instead, must replace it with two separate certificates: an all-purpose acknowledgment and a jurat. That's because the state prescribes the exact wording to be used in each.
