bocadillo
/bokaˈdiʝo/ · B2 · noun · m
sandwich
🥖 boca (mouth) + -illo (small) = a little mouthful
Bocado means a bite, from boca, mouth. The -illo ending makes it small, so a bocadillo is a little bite. In Spain that bite is a sandwich on a baguette. In Colombia it is a small block of sweet guava paste.
