Etymology
Origin of proficiency
First recorded in 1535–45; from Latin prōfici(ēns) “advancing” ( see proficient) + -ency
Explanation
If you have proficiency with something, you are pretty good at it. If you have proficiency with Spanish, you can understand and communicate well in that language. Proficiency, pronounced "pro-FISH-en-cee," comes from the Latin word proficere, meaning "accomplish, make progress, be useful." If you have achieved proficiency in something, you have done well at gaining a skill. However, having proficiency doesn't make you an expert. Still, proficiency is something to be proud of — it means you have worked hard, and if you keep going, you probably will become an expert.
