Learn French: Le freelance fait de la prospection pour éviter la précarité. - The freelancer does prospecting to avoid insecurity.

Freelance is a very common loanword in French for a self-employed person. It can be masculine (le freelance) or feminine (la freelance) depending on who you are talking about. You will also frequently see the native French term le travailleur indépendant.

Could I just use the verb prospecter instead of fait de la prospection?

Yes, you could completely say Le freelance prospecte. However, using faire de la or faire du followed by a noun is a very natural way in French to describe engaging in a professional or habitual activity. It emphasizes the process itself.

Why is précarité translated as "insecurity" here instead of "precariousness"?

While précarité is the root of the English word "precarious," in French employment contexts it specifically means financial or job insecurity. You will often hear about la précarité de l'emploi to describe temporary or unstable work situations.

Why does the sentence use pour éviter instead of an -ing equivalent?
