Quick answer
Achar often gives an everyday opinion or impression; pensar highlights the process of reflection.
A reliable test is to identify the job of the word before translating from English.
What each word does
achar
to think or find
Use achar for an opinion, impression, or discovery, especially in everyday speech.
pensar
to think or consider
Use pensar for the mental process of reflecting, planning, or forming an opinion.
How to choose
- achar: Choose achar if the sentence points to an opinion, impression, or discovery, especially in everyday speech.
- pensar: Choose pensar if the sentence points to the mental process of reflecting, planning, or forming an opinion.
Examples
Acho que vai chover.
I think it is going to rain.
Preciso pensar antes de responder.
I need to think before answering.
Common trap
Both can introduce opinions, but their patterns differ: achar que algo and pensar em algo are especially common.
Practice it in context
Pick one sentence from your real life and write it twice: once with achar, then once with pensar. If both versions feel possible, name the meaning shift.
