Is it possible to omit "the" before the word "best" in an answer to the question "What method can you suggest to improve English?" My answer is :

Immersion into the language environment is a key to best results. (I know that standard rules don't permit to omit "the" before superlative degrees of comparison but nevertheless I'm interested in it, because sometimes it is possible to do it in headlines...)


It reads OK to me without the article before "best".

More often we say that something is "the key to ~", though I wouldn't say that "a key to ~" is actually wrong.


Thank you!
