Correct spelling for the English word "agler" is [ɐɡlˈɜː], [ɐɡlˈɜː], [ɐ_ɡ_l_ˈɜː] (IPA phonetic alphabet).
I apologize, but "agler" is not a word with a dictionary definition. It seems to be an uncommon term or a typographical error as it does not appear in any reputable dictionaries or have an established meaning. It is possible that you may have misspelled the word or it may be a slang term or jargon specific to a particular industry or community. If you could provide more context or clarify the intended term, I would be happy to help you with a definition or any other information.
