When you're talking about family, biológico is a useful word. It means someone is related to you by birth, not by adoption or marriage.
For example, your birth parents are your padres biológicos. If you have a full brother or sister, they are your hermano o hermana biológico.
It helps you specify the nature of a family relationship directly.
When you are at an A2 level in Spanish, you are starting to describe things in more detail. The word biológico is really useful for this! You can use it to talk about anything connected to biology, like a parque biológico (biological park) or investigación biológica (biological research).
It also comes in handy when you want to specify family relationships that are genetic, like a padre biológico (biological father) versus an adopted father. Understanding biológico helps you be more precise in your descriptions and conversations. Keep an eye out for this word; you'll see it a lot when talking about nature, science, or family!
