interesting how the word 'diminutive' refers to making something bigger, isn't it?

Diminutive affixes indicate smallness (and in some languages, connotations of cuteness): e.g., Italian or Spanish -ino, German -chen. Augmentative affixes indicate bigness (and in some languages, pejorative connotations): e.g., Italian -one.

Ceci n'est pas un seing.
