Grammatical Constructions
& Latin Meaning
Discover how case, mood, voice, and syntax shape the meaning of every Latin sentence you read.
What Are Grammatical Constructions?
A grammatical construction is any combination of morphological forms and syntactic patterns that conveys a specific meaning. In Latin, word endings, verb forms, and clause structures all work together to tell you who does what, to whom, when, and why.
The Building Blocks of Latin Grammar
Why This Matters for AP Latin
On the AP Latin exam, you must explain how specific grammatical choices contribute to an author's meaning. This requires more than translation: you need to articulate why Caesar or Vergil chose a particular construction and what effect it produces.
Core Principle: Form Determines Function
The Case System: Who Does What
Indicative vs. Subjunctive: Mood Matters
Active vs. Passive Voice
Purpose vs. Result Clauses
| Purpose (ut + subjunctive) | Result (ut + subjunctive) | |
|---|---|---|
| Meaning | "in order to" | "so that / with the result that" |
| Signal words | ut, ne (negative) | ut after tam, tantus, ita, sic, adeo |
| Negation | ne | ut non |
| Focus | Intended goal | Actual outcome |
| Example | Venit ut videat. | Tam fortis erat ut vinceret. |
How to Analyze a Construction
Example: The Ablative Absolute
Example: Indirect Statement
Example: Relative Clause of Purpose
"Legatos misit qui pacem peterent."
"He sent ambassadors who would seek peace." (= to seek peace)
Example: Cum Clauses
| cum + Indicative | cum + Subjunctive | |
|---|---|---|
| Meaning | "when" (specific time) | "when/since/although" |
| Focus | Pinpoints a moment in time | Explains circumstance, cause, or concession |
| Example | Cum venit, gaudeo. "When he comes, I rejoice." |
Cum venisset, profectus est. "When/since he had come, he set out." |
