Italian word

efficace

effective, efficient, working well

Looks like

efficacious

producing the desired result (formal/medical term)

⚠️ The trap

Close match. But learners confuse 'efficace' (effective) with 'efficiente' (efficient). In Italian: 'efficace' = it works/achieves results; 'efficiente' = it works without wasting resources. These are distinct concepts.

To say "producing the desired result (formal/medical term)" in Italian:

efficace

"efficace" in English means:

effective, efficient, working well

Example

"Questo medicinale è molto efficace."

"This medicine is very effective."
