4Grammar and explanations
The thing becomes the subject
In "The road has been closed", English puts the road first and uses "be" with a participle. Mongolian puts –гд– inside the verb, between the stem and the ending: this is the passive. The thing acted upon becomes the subject, and very often nobody says who did it.
Цагдаа замыг хаасан.police road-ACC close-PAST"The police closed the road."
Зам хаагдсан.road close-PASS-PAST"The road has been closed."
The forms
The passive suffix is –гд–, and it has only one shape. After a vowel it goes straight on; after a consonant a linking vowel comes in, chosen by vowel harmony. A few verbs take a bare –д–.
| Plain verb | Passive | Meaning |
|---|
| хаах (to close) | хаагдах | to be closed |
| нээх (to open) | нээгдэх | to be opened, to open |
| харах (to look) | харагдах | to be seen, to be visible |
| сонсох (to listen) | сонсогдох | to be heard |
| бичих (to write) | бичигдэх | to be written |
| барих (to build) | баригдах | to be built |
| олох (to find) | олдох | to be found |
Learn these as words. The linking vowel follows no rule that this course can promise, so do not build a passive on a verb where you have not met one.
A passive takes every ending
Зам маргааш нээгдэнэ.road tomorrow open-PASS-PRES-FUT"The road will be opened tomorrow."
Түлхүүр олдсон уу?key find-PASS-PAST Q"Has the key been found?"
Энэ байшин 1960 онд баригдсан."This building was built in 1960."
Seen and heard: харагдах, сонсогдох
Two passives are everyday words. Харагдах is "to be seen, to be visible", сонсогдох "to be heard". Mongolian says what can be seen, not who sees it.
Холоос гэр харагдаж байна.far-ABL ger see-PASS-CONV be-PRES-FUT"A ger can be seen in the distance."
Тэмдэг харагдахгүй байна."No sign can be seen."
Mongolian often prefers the active
When the doer is unknown, Mongolian is also happy with an active verb and no subject at all: Гүүрийг засаж байна. "The bridge is being repaired" (literally "(they) are repairing the bridge"). Keep the passive for states and results such as хаагдсан, нээгдсэн and харагдаж байна.
