The Spanish word 'mollete', meaning 'soft bread roll', comes from the Latin word 'mollis' meaning 'soft' or 'tender'. It developed through the Spanish word 'muelle' (meaning 'soft') and added the diminutive suffix '-ete'. The diminutive ending gives it the sense of a small, soft thing - in this case, a small soft roll of bread.

A simpler related Spanish word is 'muelle', which means 'soft' or in modern Spanish is also used to mean 'spring' (as in a coiled metal spring) or 'dock/pier'. The connection between these meanings comes from the original sense of something soft or yielding - a spring is flexible and yields to pressure, while a dock yields to the movement of water and ships.

The English word 'mollify' shares the same Latin root 'mollis'. 'Mollify' means 'to soften' in both a literal and figurative sense, most commonly used to mean 'to calm someone down' or 'to make less harsh'. Another related English word is 'mollusc/mollusk', referring to soft-bodied animals like snails and slugs, which also comes from Latin 'mollis'.
