Hi,
Trying to get to grips with thr word "augment" and most definitions tell me that it is a word meaning to "make bigger", whereas i always thought it meant "to enhance", which doesn't necessarily mean to make bigger, right? It might help if you think of it as 'make something bigger or better'. This would bring in the meaning of 'enhance', which is certainly valid.
Anyway, please can you guys have a quick read through the following sentence and let me know if it works well? Feel free to make any changes your, more knowledgable brains see fit.. 'd be most grateful, as I always am when I post here.
"This project aims to augment the efficiency of the conference website building process, by introducing a web-based content management system, essentially eliminating the need for a web developer."
I wouldn't entirely say it's wrong to 'augment efficiency', but it doesn't sound good. I have trouble grasping what it means to make efficiency bigger or better? I'd prefer 'improve efficiency'.
You are trying to augment your vocabulary. I hope that my comments have augmented your understanding. 
Best wishes, Clive
