Comer sano.

The Spanish phrase 'Comer sano' translates literally to 'to eat healthy.' Let's break down the etymology of each word. **Comer:** This verb comes from the Latin 'comedere,' which means 'to eat up, consume.' 'Comedere' itself is a compound of the prefix 'com-' (meaning 'with, together, thoroughly') and 'edere' (meaning 'to eat'). The root 'edere' is an ancient Indo-European root found in many languages, related to English 'eat,' German 'essen,' and Sanskrit 'ad-.' Over time, in Vulgar Latin and then in Old Spanish, 'comedere' evolved into 'comer,' losing the initial 'co-' sound in the infinitive but retaining the meaning of consuming food. **Sano:** This adjective derives from the Latin 'sanus,' meaning 'healthy, sound, sane.' The Latin 'sanus' was used to describe both physical and mental well-being. It is the root for many English words like 'sane,' 'sanitary,' 'sanity,' and 'sanatorium.' In Spanish, 'sanus' directly evolved into 'sano,' retaining its core meaning of being in good health. The concept of 'sano' extends beyond just physical health to imply a state of well-being, integrity, and being free from harm or defect. Therefore, 'Comer sano' is a direct and literal construction in Spanish, combining the inherited Latin verb for eating with the inherited Latin adjective for healthy, to convey the idea of consuming food in a way that promotes good health and well-being. The phrase is widely understood and commonly used in Spanish-speaking cultures to encourage healthy eating habits.
