Quick answer
Adotar chooses and begins using something. Assumir takes responsibility, control, or a role.
A reliable test is to identify the job of the word before translating from English.
What each word does
adotar
to adopt
Use adotar for choosing a policy, method, practice, position, name, or child as one’s own.
assumir
to assume or take on
Use assumir for accepting responsibility, a role, control, risk, or publicly stated position.
How to choose
- adotar: Choose adotar if the sentence points to choosing a policy, method, practice, position, name, or child as one’s own.
- assumir: Choose assumir if the sentence points to accepting responsibility, a role, control, risk, or publicly stated position.
Examples
A escola adotou um novo método.
The school adopted a new method.
Ela assumiu a direção da empresa.
She took over the management of the company.
Common trap
English “adopt a position” may be adotar uma posição; “assume a position” may be assumir um cargo. The object reveals the direction.
Practice it in context
Pick one sentence from your real life and write it twice: once with adotar, then once with assumir. If both versions feel possible, name the meaning shift.
