Clitic Pronouns with Modal Verbs
In Italian, when a modal verb is followed by an infinitive, you have two choices for pronoun placement: Lo voglio vedere (before the modal) or Voglio vederlo (attached to the infinitive).
How It Works
When a sentence contains a modal verb (potere, volere, dovere) or sapere (meaning 'to know how to') followed by an infinitive, the pronoun has two possible positions:
1. Proclisis (Climbing): The pronoun is placed immediately before the conjugated verb.
Example: Lo so fare (I know how to do it).
2. Enclisis (Attachment): The pronoun is attached to the end of the infinitive (which drops its final -e).
Example: So farlo.
Key Rules:
- Reflexive Verbs & Auxiliaries: The position of the pronoun determines the auxiliary in compound tenses. If the pronoun climbs, you must use essere (Mi sono dovuto alzare). If it is attached, you use avere (Ho dovuto alzarmi).
- Direct Object Agreement: If a direct object pronoun (lo, la, li, le) climbs, the past participle must agree with it (e.g., Le ho volute vedere).
- Auxiliary Exceptions: While the auxiliary usually follows the main verb, if the main verb is essere, the auxiliary is always avere (Ho dovuto essere forte). Additionally, sapere almost always takes avere (Ho saputo uscire), unless a reflexive pronoun climbs (Mi sono saputo trattenere).
- Impersonal 'Si': With impersonal constructions, the si can precede the modal (Si può fare) or follow the infinitive (Può farsi). If another pronoun is present, si follows it (Lo si può fare).
- Clusters: Combined pronouns must move together as a single unit.
Examples (6)
- Lo voglio comprare.
I want to buy it.
Word by Word: It I want to buy.
Here the direct object pronoun 'lo' (it) climbs before the modal verb 'voglio'.
- Voglio comprarlo.
I want to buy it.
Word by Word: I want to buy-it.
The pronoun 'lo' is attached to the infinitive 'comprare', which drops its final 'e'.
- Ti posso richiamare più tardi?
Can I call you back later?
Word by Word: You I can call back more late?
In questions, placing the pronoun before the modal is very common and natural in spoken Italian.
- Mi devo svegliare presto.
I have to wake up early.
Word by Word: Myself I must wake up early.
With reflexive verbs, both positions are equally correct; you can also say 'Devo svegliarmi presto'.
- Non posso dirtelo.
I can't tell it to you.
Word by Word: Not I can tell-to you-it.
When using combined pronouns (ti + lo = te lo), they stay together at the end of the infinitive.
- L'ho dovuta chiamare tre volte.
I had to call her three times.
Word by Word: Her I have had to call three times.
When a direct object pronoun climbs, the past participle must agree in gender and number with it (la -> l' ... dovuta).
Common Mistakes
Placing the pronoun between the modal and the infinitive.
Voglio lo vedere.Lo voglio vedere. / Voglio vederlo.The pronoun can never sit between the two verbs. It must either be at the very beginning or attached to the very end.
Splitting combined pronouns.
Te voglio dirlo.Te lo voglio dire. / Voglio dirtelo.Combined pronouns are inseparable. They must both climb or both attach.
Using the wrong auxiliary with climbed reflexive pronouns.
Mi ho dovuto alzare.Mi sono dovuto alzare.If a reflexive pronoun climbs before the modal verb in the past tense, you must use 'essere' as the auxiliary.

To learn the placement of pronouns with modal verbs, a learner needs to be comfortable with the conjugation of 'dovere', 'potere', and 'volere', recognize the forms of direct (and indirect) object pronouns, and understand the standard rule for attaching pronouns to the end of an infinitive verb.
