The word for ‘impatient’ in Spanish is impertinente or impaciente.
When describing someone who is unable to wait or who lacks patience, you would typically use impaciente. This word is derived from the Latin ‘impatientem,’ which means not able to endure.
For example, you could say: Ella es impaciente, which translates to ‘She is impatient.’
On the other hand, impertinente can also denote impatience, but it more commonly refers to someone who is disrespectful or rude, so it’s important to use the right context when choosing your words.
