The word for today is CULPA, which means fault

Not to be confused with PULPA, which means pulp

Not to be confused with PULPO, which means octopus

Bonus:

PULPITO means baby octopus but it also means pulpit

Not to be confused with PALPITO, an irregular heart rhythm

 

Application:

It’s the baby octopus’ fault that the father octopus has arrhythmia

Es culpa del pulpito que el papá pulpo tenga pálpito
