Meminisse is the infinitive of the defective Latin verb meminī and means "to remember." Even though it looks like a perfect infinitive, it translates with present meaning. It appears in Aeneas's speech in Aeneid Book 1 (forsan et haec olim meminisse iuvabit), part of the required AP Latin syllabus.
Meminisse is the infinitive of meminī, a defective verb. Defective means the verb is missing most of its forms. Meminī only exists in the perfect system, so its perfect forms carry present meaning. Translate meminisse as "to remember," not "to have remembered."
The word matters for AP Latin because of one famous line. After the storm wrecks his fleet, Aeneas rallies his exhausted men in Book 1 with forsan et haec olim meminisse iuvabit, roughly "perhaps someday it will be pleasing to remember even these things." Grammatically, meminisse works as a subject infinitive of the impersonal verb iuvabit. Literally, "to remember will please." The line captures one of the Aeneid's biggest ideas, that present suffering becomes meaningful when it is remembered as part of a larger destiny.
Meminisse lives in Unit 4 (Vergil's Aeneid, excerpts from Books 1 and 2), alongside Topic 4.1's opening lines. It hits the vocabulary learning objectives directly. AP Latin 4.1.A asks you to define Latin words and phrases, and AP Latin 4.1.B asks you to identify their meaning in context. Meminisse is a classic test of both, because a literal-looking translation ("to have remembered") is actually wrong. The line it appears in also feeds AP Latin 4.1.D, summarizing implied meaning, since Vergil tells us right after the speech that Aeneas is faking the optimism (spem vultu simulat). The word is small, but it sits inside one of the most quoted and most translated sentences in the whole syllabus.

Aeneas (Unit 4)
Meminisse is the emotional center of Aeneas's pep talk to his men. He frames their suffering as future memories worth having, which shows the leadership and pietas that define his character, even while he privately despairs.
Aeneid (Unit 4)
The whole epic is built on memory. Juno remembers old grudges, Aeneas remembers Troy, and Rome will remember its founders. Meminisse names that theme in a single word.
in medias res (Unit 4)
Because Vergil starts the plot in the middle of things, Aeneas's promise that remembering will someday be pleasant points both backward (the fall of Troy, told in Book 2) and forward (the founding of Rome). The word meminisse only works because of where the story begins.
foundation legend (Unit 4)
In the same speech, Aeneas says tendimus in Latium, we are heading for Latium. Remembering hardship is how the Trojans' suffering becomes Rome's foundation story, which is the legend the entire Aeneid exists to tell.
This is exactly the kind of word the translation free-response question targets. The 2025 AP Latin exam's Translation Q1 used the passage containing meminisse (forsan et haec olim meminisse iuvabit), and full credit requires rendering it with present meaning, "to remember." You also need to handle the impersonal construction, where meminisse is the subject of iuvabit, so something like "it will be pleasing to remember" earns the point and "to have remembered" does not. Multiple-choice questions can test the same skill under AP Latin 4.1.A and 4.1.B by asking for the best translation of meminisse in context. The line is also fair game for short-answer questions about Aeneas's characterization, since the speech contrasts with his hidden grief.
Both come from the same memory root, but they mean different things. Meminisse means to remember, to hold something in your own mind. Memorare means to recount or relate, to put a memory into words for someone else. You see memorare in the required Topic 4.1 lines themselves, when Vergil tells the Muse 'mihi causas memora' (line 8), 'recount the causes to me.' On a translation question, swapping the two costs you the point.
Meminisse is the infinitive of the defective verb meminī and means "to remember," with present meaning despite its perfect form.
In Aeneid Book 1, meminisse is the subject infinitive of the impersonal iuvabit, so the phrase means "it will be pleasing to remember."
The 2025 AP Latin Translation Q1 included this exact passage, so translating meminisse correctly is a proven point-earner.
Aeneas's line about remembering hardship is partly a performance, since Vergil says he fakes hope on his face, which makes it great evidence for characterization questions.
Don't confuse meminisse (to remember) with memorare (to recount), which appears as 'memora' in line 8 of the required proem.
Meminisse means "to remember." It is the infinitive of meminī, a defective verb that only has perfect-system forms, so its perfect forms translate with present meaning.
No. Even though meminisse is formed like a perfect infinitive, meminī is defective and its perfect forms carry present meaning. On the AP translation rubric, "to have remembered" is wrong; "to remember" is correct.
Meminisse means to remember something yourself, while memorare means to recount or relate it to others. You see both on the AP syllabus, since Vergil asks the Muse to 'memora' the causes in Aeneid 1.8 and Aeneas uses meminisse in his speech later in Book 1.
It appears in Aeneas's speech to his shipwrecked men in Book 1, in the line 'forsan et haec olim meminisse iuvabit,' meaning "perhaps someday it will be pleasing to remember even these things." This passage is on the required AP Latin reading list.
Mainly through literal translation. The 2025 exam's Translation Q1 included the passage with meminisse, where you needed present meaning ("to remember") and the impersonal construction with iuvabit ("it will be pleasing to remember") to earn full credit.
