The personal infinitive is a verbal structure that usually poses some difficulties for Portuguese language learners. In fact, we are talking about a conjugation structure that is quite simple and lacks irregular verbs, which makes its usage much easier. However, on the other hand, we are dealing with a verbal structure that has no equivalent in any other language, making it unique and somewhat challenging.
To use the personal infinitive, we need to correctly identify its connectors, and this is usually the most challenging part for Portuguese language learners.
The personal infinitive is used in sentences about the present, the past, or the future. The rule is to conjugate/inflect the verb following its connectors.
Here is the list of connectors that we consider most important. The connectors we consider most important are the ones we use most frequently.
CONNECTOR 1: Impersonal expressions, for example: ‘É bom‘ = ‘It is good,’ ‘É interessante‘ = ‘It is interesting,’ ‘É importante‘ = ‘It is important,’…
CONNECTOR 2: Preposition ‘PARA‘ when used with the meaning of ‘in order to‘ or ‘so that‘.
CONNECTOR 3: ‘Antes de‘ = ‘before’ and ‘depois de’ = ‘after’.”
Regarding the correct conjugation of the personal infinitive, here is a list of endings using the verb ‘IR‘ = ‘to go’ as an example.
É BOM (conector)… Eu ir, Tu ires, Ele ir, Nós irmos, Eles irem
