Definition
*Appello* is a Latin term from the civil law meaning "I appeal." It denotes the formal verbal act by which a party announced an appeal, spoken or recorded in the first person singular as the operative declaration initiating appellate proceedings. In Roman civil procedure, *appello* was the specific word a party uttered or caused to be inscribed in the official record (*apud acta*) to perfect an appeal from a judgment. The utterance was performative: saying or recording *appello* was itself the legal act, not merely a description of intent.

Common Language
Modern common usage (Wiktionary): No standard English entry; treated as a Latin word meaning "I call," "I name," or "I appeal to."
Historical common usage (Webster's 1913): Not separately entered; derives from the Latin *appellare*, to call upon, address, or appeal.
The gap here is one of register and function. In ordinary Latin, *appello* means broadly "I address" or "I call upon." In the civil law, it is a narrow term of art — a specific, operative declaration that triggers the appellate process. The difference between addressing someone and formally perfecting an appeal is legally decisive.

Why It Matters in Research
*Appello* appears almost exclusively in scholarship and commentary on Roman civil procedure and in treatises tracing the historical roots of appellate practice. Researchers encountering the term in English-language legal dictionaries are typically working backward from modern appellate doctrine to its civil law antecedents.
The key navigational point: *appello* does not describe an appeal in the abstract. It describes the formal, ritualized verbal or written act of making one. Historical sources that discuss Roman appeals in technical detail — particularly commentaries on the Digest, title 49.1 — use *appello* as the operative word, distinct from *appellatio* (the appeal as a proceeding or institution). Conflating the verb with the noun leads to imprecision when tracing how appellate practice evolved from Roman forms into canon law, and later into common law equity practice.
Corpus researchers should note that Black's (1st and 2nd editions) and Burrill treat this term briefly and consistently, suggesting it was included for completeness in covering civil law vocabulary rather than because it had active currency in American legal practice. It is a gateway term — its value is in unlocking the surrounding civil law appellate apparatus, not in standing on its own as a doctrine.
The reference to *apud acta* (literally, "in the presence of the record") in both Black's editions is the substantive connection: appeal by *appello* had to be recorded in the official proceedings to be effective. This formality distinguishes the Roman model from later common law practice, where appellate procedures developed differently and without this specific verbal trigger.

Historical Dictionary Support
Burrill's Law Dictionary and both editions of Black's Law Dictionary are in close agreement: all three define *appello* as the Latin civil law term for "I appeal" and identify the form of making an appeal *apud acta*, with citation to Digest 49.1.2. The first edition of Black's includes a slight elaboration noting a conditional form — an appeal conditioned on a future event (*de bene esse*) — which the second edition omits, suggesting editorial streamlining rather than substantive disagreement.
The Digest citation (49.1.2) is genuine and foundational; Ulpian's treatment of appeals in that title is the primary Roman-law source for how *appello* functioned procedurally.
What the historical dictionaries do not do is trace the term forward. They offer no bridge from Roman practice to medieval canon law appellate procedure, nor to the equity practice of early American courts. Researchers needing that genealogy must go beyond the dictionary shelf.
