I face an issue with a catch-phrase on my site.
English is not my native language, and I just can't solve this issue.
I have a catch-phrase, and by the rules of grammar, it needs the article an:
Make test from your materials. Without an effort. Without wasting time
However, I have never seen this kind of usage of articles in slogans (or I just didn't notice), and it seems redundant to me.
Can I not include the article in the slogan, just because it is not a part of natural speech, and should be compact/strong? I mean, in order to sound certain, like "I'm loving it". By the way, is that also a formal mistake - to use love with -ing?
