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."
