Translation guide
The English word "apt" has several distinct meanings. This guide covers the most common uses for learners: being suitable or appropriate, having a natural tendency, and being quick to learn.
Describing something that is fitting, well-chosen, or right for the situation.
A common and versatile adjective meaning appropriate, suitable, or pertinent. Can be used in both formal and everyday contexts.
Describing someone or something that is likely to do something, often something undesirable.
Attach to verb stem to mean 'apt to do', 'tend to'. Often used for negative habits or tendencies.

Describing a person who is intelligent and learns quickly.
