sumamente
/ˌsumaˈmente/ · B2 · adv
extremely
⬆️💯 sumamente = Latin summus (highest) + -mente, so 'to the highest degree'
Sumamente comes from Spanish suma, 'sum' or 'top total', from Latin summus, 'highest'. The ending -mente works like English -ly. So it literally means 'highest-ly', which is why it means extremely or highly.
