Could you show me how to use the word as per in a sentence? Can I make sentences something like the following:
I changed the image as per the suggestion of my boss.
Or could you give me an alternative to the phrase?
As per means "in accordance with", so "following something that has been decided".
Such as your example:
I have a "pet peeve" about "as per" and prefer my staff not to use it, because it raises a flag with me that someone is saying "not my fault, don't blame me!" Your sample sentence would do better, in my opinion, as one of these:
These all have slightly different meanings and emphasis. (For example, the second one is more likely to be an answer to "what did you do this morning?" than "why has this image changed?", which the first and third could be answers to.) Your sentence uses "as per" correctly as far as grammar and syntax goes, but it's not a phrase you should go out of your way to use.
If you’re set on using per, then you should say simply:
Other possibilities include:
There is a mistaken assumption here that as per has a valid usage. It doesn’t; it’s just one in common use, and is valid only by that sole metric alone.
As per is always redundant; you don’t ever need the superflous as portion of the phrase. Indeed, the OED says that as per usual is “humorous slang”.
