Little mouse
"The name we give to this little animal is very recent. The word 'mouse' is a diminutive of 'rat', a larger animal. The word 'rat' would be created by what these animals do when they gnaw everything they find in their path, therefore, its origin is onomatopoeic."
Shrew (Musaraña)
"From the Latin 'mus araaneus', shrews are insectivorous mammals similar to mice but with a very elongated snout. 'Mus' reminds us of the English word 'mouse' and it refers to exactly that, mouse, and ' araneus' would mean something like 'arachnoid'. Attention, there goes Spider-Mouse!"
Calculate
"Do you like numbers and doing additions and subtractions? Then this will seem curious to you. 'Calculate' derives from the Latin 'calculus' which meant small stone, and who has not used the abacus to start making calculations? The fact of Being able to see and touch numbers has helped us get started in mathematics since ancient times, preventing them from becoming entrenched like a painful kidney stone!"
Paint
"The word 'painting' comes from the Latin 'pingere', but do you know what it meant? Taking the color of fruits, and the first artists had to take the pigments and colors from what surrounded them in nature: red of strawberries, the yellow of limes or the green of pears."
