estimar
/estiˈmaɾ/ · B2 · verb
to think, to believe
🤔⚖️ sounds like 'estimate' (the English cousin) - same Latin root aestimare
Spanish estimar and English estimate and esteem all come from Latin aestimare, 'to value or appraise'. Valuing something gives you all three senses: you esteem it, estimate its worth, and so believe or think it is worth something.
