Clitic Climbing with Modals
When using a modal verb (like poder, dever, or querer) followed by an infinitive, the object pronoun (me, te, o, a, etc.) can often attach to either verb. This movement is called 'clitic climbing'.
How It Works
Clitic climbing occurs with a specific group of verbs known as 'restructuring verbs.' These include:
- Modals: poder (can), dever (must), querer (want).
- Aspectuals: começar a (start), acabar de (just finished).
- Motion: ir (go), vir (come).
Regional Differences:
In European Portuguese (EP), climbing is very common. You will often hear Quero-te ver. Note that in EP, you cannot start a sentence with a pronoun, so Te quero ver is considered incorrect, requiring either the climbed version (Quero-te ver) or the standard version (Quero ver-te).
In Brazilian Portuguese (BP), the pronoun usually sits in the middle without a hyphen: Quero te ver. The climbed version with a hyphen (Quero-te ver) is rare in speech.
Morphological Changes:
If the pronoun climbs to a verb ending in a nasal sound (-m, -ão), it changes (e.g., podem + o becomes podem-no). If it stays with the infinitive, the -r is dropped (e.g., ajudar + o becomes ajudá-lo).
The Negation Rule:
If a 'trigger' word like não is present, the pronoun is pulled to the front of the whole verbal chain: Não te posso ajudar.
Examples (5)
- Eu posso-te ajudar amanhã.
I can help you tomorrow. (European Portuguese climbed style)
Word by Word: I can-you help tomorrow.
Here, the pronoun 'te' has climbed from the verb 'ajudar' to the modal 'posso'.
- Eu posso ajudar-te amanhã.
I can help you tomorrow. (Standard/European style)
Word by Word: I can help-you tomorrow.
The pronoun 'te' remains attached to the main verb 'ajudar'.
- Eu posso te ajudar amanhã.
I can help you tomorrow. (Brazilian Portuguese style)
Word by Word: I can you help tomorrow.
In Brazilian Portuguese, the pronoun typically floats in the middle without a hyphen.
- Não o quero fazer agora.
I don't want to do it now.
Word by Word: Not it want to-do now.
The negative word 'não' triggers proclisis, pulling the pronoun to the very front of the verb chain.
- Eles devem-no visitar hoje.
They must visit him today.
Word by Word: They must-him visit today.
Because 'devem' ends in a nasal sound, the climbed pronoun 'o' becomes 'no'.
Common Mistakes
Using the pronoun twice (Double Clitics).
Quero-te ajudar-te.Quero-te ajudar. / Quero ajudar-te.You must choose one position for the pronoun; you cannot place it on both verbs simultaneously.
Using enclisis on the auxiliary when a negative trigger is present.
Não posso-te ajudar.Não te posso ajudar. / Não posso ajudar-te.The word 'não' prevents the pronoun from attaching to the end of the first verb (posso-te). It must either move to the front or stay at the very end.
How It Connects
Learn This First
To learn clitic climbing with modals, you need to be comfortable with direct object pronouns and the two standard ways they attach to verbs (before or after). This pattern specifically addresses the flexibility of placing these pronouns when a modal verb is paired with an infinitive.

Level 1 - Proclisis (Pronoun Before Verb)
Climbing is a specific type of pronoun placement that often involves choosing between proclisis and enclisis.
Level 2 - Brazilian vs European Clitic Placement
Clitic climbing preferences are one of the primary differences between Brazilian and European pronoun usage.
Level 3 - -lo/-laObject Pronoun After -R/-S/-Z Verbs
When the pronoun does NOT climb and stays with the infinitive, it often triggers these spelling changes.
Level 3 - -no/-naObject Pronoun After Nasal-Final Verbs
When the pronoun climbs to an auxiliary ending in a nasal sound, it triggers these spelling changes.
