Case and point: helado, Spanish for “ice cream” (and related words: helar for “to freeze”, and hielo, “ice”). All of these come from the Latin for gelare for… gelatin. And what is sweetened gelatin for mass consumption if not the brand… jello!
We can see the pattern best if we remember that the silent h- is very similar to the barely audible soft g- and soft j- sounds in English. Thus, the h-l-d of helado maps to the g-l-t of gelatin!
