Learn Portuguese (Portugal): Redijo o projeto a fim de financiar a investigação. - I draft the project in order to fund the research.

We use a fim de followed by the infinitive (financiar) because both verbs share the same subject (I am the one drafting and I am the one funding). If the subjects were different (for example, I draft it so that they can fund it), you would need a fim de que followed by the subjunctive.

Why is the verb redigir spelled with a 'j' in redijo?

This is a spelling change to preserve the pronunciation. The 'g' in redigir has a soft sound. If we kept the 'g' before the letter 'o' to spell redigo, it would make a hard sound like in the English word go. Changing it to a 'j' maintains the original soft sound.

Could I just use para instead of a fim de?

Absolutely. The word para also means in order to and is grammatically interchangeable here. However, a fim de is more formal and elevates the tone of the sentence, which perfectly matches the professional context of drafting a funding project.

Is investigação the standard word for research? I have also seen pesquisa.
