deficio

• difficiō (Medieval Latin)

From de- +‎ facio.

• (Classical) IPA^(key): /deːˈfi.ki.oː/, [d̪eːˈfɪkioː]
• (modern Italianate Ecclesiastical) IPA^(key): /deˈfi.t͡ʃi.o/, [d̪eˈfiːt͡ʃio]

dēficiō (present infinitive dēficere, perfect active dēfēcī, supine dēfectum); third conjugation iō-variant

1. (intransitive, ab + ablative or ad + accusative) to move away, leave, withdraw, break away

   ab aliqua re deficere ― to break away from something

2. (intransitive) to be exhausted, run out, fail
3. (intransitive) to be discouraged, disappoint or let down
4. (intransitive) to finish up, die
5. (transitive) to forsake, desert or abandon
6. (passive voice, reflexive) to be lacking in, to fall short, have shortcomings, fail

¹At least one use of the archaic "sigmatic future" and "sigmatic aorist" tenses is attested, which are used by Old Latin writers; most notably Plautus and Terence. The sigmatic future is generally ascribed a future or future perfect meaning, while the sigmatic aorist expresses a possible desire ("might want to").

• 526–527, Priscianus Caesariensis, Institutiones Grammaticae, De Dictione

  vides ergo per se ipsam syllabam deficere praedictorum ratione nec aliter posse examussim tractari, nisi posita sit in dictione.

  (please add an English translation of this quotation)

• 845, the same as it appears in the St. Gall Priscian Glosses

  uidesgͦ p̛se ipsam syllabã difficere p͞dictor̄ ratione, necalit̄ posse examosim tractari n͗ posita indictione sit.

  So you see that in and of itself the syllable is insufficient because of the aforementioned, and cannot otherwise exactly be used unless it is placed in a word.
