what is it?
Turkish expresses obligation and necessity not only through the suffix -mAlI (covered at A2) but also through a set of lexical periphrases: zorunda, gerek, lazım, and şart. Each combines a nominalized verb with one of these predicates to state that something must be done. The key distinction from -mAlI is source of obligation: these periphrases typically signal external or objective necessity — a rule, a circumstance, or a practical requirement — rather than the speaker's personal judgment or advice.
when to use it
zorunda — use for strong external compulsion: a law, a rule, or a situation that leaves no choice. It is the closest Turkish equivalent of «have to» in the sense of being forced.
şart — use for strong necessity framed as an essential condition: «it is essential / a must». Slightly more formal than zorunda and often used in written or emphatic speech.
gerek / gerekiyor — use for milder, practical necessity: «need to». Gerekiyor (the verb gerekmek in present tense) is common in everyday speech.
lazım — use for mild, everyday necessity: «need to / necessary». Very frequent in spoken Turkish and interchangeable with gerek in most contexts.
Strength of obligation: zorunda / şart (stronger) → gerek / lazım (milder). When the obligation comes from an external authority or unavoidable circumstance, prefer zorunda. When it is simply a practical need, lazım or gerekiyor is the natural choice.
formation
The nominalizer used depends on the predicate. This is the most important structural rule to learn.
zorunda takes the -mAk infinitive: gitmek zorunda-yım. The copula suffix (personal ending) is added directly to zorunda.
gerek / lazım / şart take the -mA verbal noun plus a possessive suffix agreeing with the subject: git-me-m lazım (my going is necessary → I need to go).
The table below shows the full personal paradigm for each predicate using the verb gitmek (to go).
| person | -mAk zorunda + copula | -mA+poss lazım | -mA+poss gerek | -mA+poss şart |
|---|---|---|---|---|
| ben (I) | gitmek zorundayım | gitmem lazım | gitmem gerek | gitmem şart |
| sen (you sg) | gitmek zorundasın | gitmen lazım | gitmen gerek | gitmen şart |
| o (he/she/it) | gitmek zorunda | gitmesi lazım | gitmesi gerek | gitmesi şart |
| biz (we) | gitmek zorundayız | gitmemiz lazım | gitmemiz gerek | gitmemiz şart |
| siz (you pl) | gitmek zorundasınız | gitmeniz lazım | gitmeniz gerek | gitmeniz şart |
| onlar (they) | gitmek zorundalar | gitmeleri lazım | gitmeleri gerek | gitmeleri şart |
For gerekiyor (the verb form), the structure is: -mA+possessive + gerekiyor. Example: bitmemiz gerekiyor (we need to finish). The verb gerekmek is conjugated normally and can appear in any tense.
examples in context
common pitfalls
Using -mAlI where external obligation calls for zorunda.
-mAlI expresses the speaker's own judgment or advice («I think you should…»). When the obligation comes from outside — a law, a deadline, a situation — use zorunda instead.
✗ Vizeyi almak malıyım. (sounds like personal advice to yourself)
✓ Vizeyi almak zorundayım. (the law/rules require it)
Wrong nominalizer: using -mAk with gerek/lazım/şart.
Only zorunda takes the plain -mAk infinitive. The predicates gerek, lazım, şart require the -mA verbal noun with a possessive suffix that matches the subject.
✗ Gitmek lazımım. (wrong nominalizer + wrong structure)
✓ Gitmem lazım. (-mA + 1sg possessive)
Dropping the personal ending on zorunda.
The word zorunda acts as a predicate and must carry the copula suffix to agree with the subject. Leaving it bare (3rd person) when you mean 1st or 2nd person is a common slip.
✗ Ben gitmek zorunda. (bare form = 3rd person reading)
✓ Ben gitmek zorundayım. (1sg copula -yım)
