proskyneo. Go on, say it. Say it out loud. Pros-koon-eh-o.

Or, did you say pros-koon-glottal stop-o?

You know the glottal stop. It’s what you do when you say the word “button” in normal speech, if you’re American anyways. Also, the glottal stop is infamously employed by Cockney speakers (cf. Ricky Gervais). There’s nothing wrong with the glottal stop. I’m not saying there is, but I don’t think it belongs in an anglophone’s pronunciation of Greek verbs, or any ‘phones pronunciation for that matter.

So please stop glottal stopping. And perhaps go with the open-mid front unrounded vowel instead.

Note, I’m not being a prescriptivist; a prescriptivist would say, “Don’t say…” I’m only kindly requesting you don’t. =)
