The Spanish word 'alteración' comes from the Late Latin word 'alteratio', meaning 'alteration'. This Late Latin term was formed by combining the Latin verb 'alterare' (meaning 'to make different') with the suffix '-tio' (which forms action nouns). The verb 'alterare' itself was derived from the Latin word 'alter', meaning 'other'.

The development from Latin to Spanish followed a common pattern where the Latin '-tio' suffix evolved into Spanish '-ción', while maintaining its original meaning of indicating an action or process.

Several common Spanish words share this Latin root 'alter-', including 'alterar' (to alter or change), 'otro' (other, from Latin 'alter'), and 'alternativa' (alternative). These words all carry the core meaning of 'otherness' or 'change' from their common ancestor.

English speakers can easily connect 'alteración' to several similar English words like 'alteration', 'alter', and 'alternate'. These English words share the same Latin ancestry and maintain similar meanings related to change or difference. The English word 'alteration' is particularly close in both meaning and form to the Spanish 'alteración', making it easy to remember.
