Did you know?
- The word eres is a rare linguistic fossil from Latin. While most modern Spanish verbs evolved from the Latin present tense, eres is actually a survivor from the Latin future tense form eris.
- Depending on the region, calling someone tonto can be used as a term of endearment between romantic partners or friends, similar to 'silly'.
- While tonto is often mild, the word estúpido can feel significantly more offensive and cold in many Spanish-speaking cultures than 'stupid' does in English.
