When the subject is also affected. Three voices, not two: active, middle, passive. Identical present forms, the υπο + genitive agent marker, deponent verbs (middle form, active meaning), the verbs that change meaning across voices, and the divine passive in the Beatitudes.
| Voice | Sense | Example |
|---|---|---|
| Active | Subject performs the action | "I loose" |
| Middle | Subject acts on or for itself | "I loose for myself" |
| Passive | Subject receives the action | "I am loosed (by someone)" |
English has only active and passive. Middle is uniquely Greek — we use reflexive pronouns ("he hits himself") or just rephrase. Greek has a dedicated form.
Imagine you're cooking yourself dinner.
λουω active = "I wash (something)." λουομαι middle = "I wash myself" (i.e., I bathe).
Greek's middle and passive use identical endings in the present (and in the imperfect, Lesson 14). The form alone is ambiguous.
| Person | Singular | Plural |
|---|---|---|
| 1st | -ομαι | -ομεθα |
| 2nd | -η (-ει) | -εσθε |
| 3rd | -εται | -ονται |
The aorist (Lesson 15) and aorist passive (Lesson 17) finally separate them. In present and imperfect, you read context to decide.
When grammars write "middle/passive," they mean these two distinct voices happen to share identical forms in certain tenses (present, imperfect, perfect).
They do NOT mean there is a third voice called "middle-passive."
In every real sentence, the form is either middle OR passive. Always make a decision: is the subject acting on itself (middle) or being acted on by another agent (passive)?
| Person | Singular | Plural |
|---|---|---|
| 1st | λυομαι | λυομεθα |
| 2nd | λυη (λυει) | λυεσθε |
| 3rd | λυεται | λυονται |
Each form is double-glossed: "I am loosed" (passive) OR "I loose for myself" (middle). Decision belongs to context.
When you encounter a present mid/pass form, run this check:
When you want to say "by whom" the passive action is done, Greek uses υπο + genitive. This is the standard NT construction and a strong signal of passive voice.
Case-shift signal: υπο + acc = "under" (spatial). υπο + gen = "by" (passive agent).
ερχομαι looks middle (-ομαι) but means "I come" (active). γινομαι looks middle but means "I become."
These are deponents — always middle/passive in form, always active in meaning. The lexicon will tell you.
The -ομαι ending in the lexical form is the giveaway: this verb is deponent. Translate the form actively.
Why does Greek do this? Linguistically, "coming" and "becoming" are inherently subject-affecting actions — your motion changes you.
The middle voice's "subject-affectedness" fits perfectly. Some scholars argue we shouldn't even call these "deponent" — they're just middles for actions that necessarily involve the subject.
English: parousia (παρουσια, "coming, presence" — from ερχομαι + παρα); -genesis (from γινομαι's root γεν-).
Reading habit: when the lexical form ends in -ομαι, expect a deponent. Translate as active — never "for themselves."
A small but important class of verbs shift their lexical meaning when they switch voice — not just grammatical force but the actual word's meaning.
Mark 6:34: και ηρξατο διδασκειν αυτους = "and he began to teach them" — never "he ruled to teach them."
When the lexicon shows separate active and middle entries with different glosses, treat them as effectively two verbs sharing a root. Use the meaning that matches the voice; watch the case it governs (αρχω takes gen; αρχομαι takes infinitive).
When a passive verb appears with no explicit agent, it often implies God as the agent. Jewish writers tended to avoid the divine name and used passive constructions as a circumlocution.
"Blessed are those who mourn, for they shall be comforted." (Matt 5:4). The passive future παρακληθησονται has no explicit agent — the implied agent is God.
The Beatitudes, the Sermon on the Mount, and Pauline soteriology are saturated with divine passives. Learn to spot them.
"The Word became flesh."
"Christ died · was buried · has been raised."
The voice of each verb tells you who acts and who is acted upon.
"The time has been fulfilled and the kingdom of God has drawn near."
The middle voice expresses subject involvement. The subject does the action and is somehow affected by it — doing it for itself, on itself, or with self-interest.
James 4:3: αιτεισθε και ου λαμβανετε ("you ask and do not receive"). The verb αιτεισθε is middle — implying you ask for yourselves, with self-interest. James continues: "you ask wrongly, that you may spend it on your pleasures." The middle voice has already telegraphed the problem.
By Koine times, many verbs had become "middle-only" (deponents) where form-meaning correlation had eroded. ερχομαι doesn't carry middle force; it's just how the verb conjugates.
When you encounter a middle-voice verb, slow down. Is this a deponent, or is the writer choosing the middle voice for a reason? When the choice is meaningful, you've caught a layer English typically loses.
Three voices, identical present mid/pass forms, the four-step diagnostic, the υπο + gen agent marker, deponents, voice-meaning shifts, and the divine passive. The form is ambiguous; context decides.
