Does any Greek word have a geminate consonant after a long vowel?

Question

I recently noticed a pattern in loans from Hebrew into Greek: the letter šin (or sin, or łin if you're really archaic) is transcribed σσ after a short vowel, σ elsewhere.

My knowledge of Classical Hebrew and Aramaic is weak, so this gemination might be a feature of those languages for all I know. But off the top of my head, I also can't think of any Greek word with a doubled consonant after a long vowel.

Does any such word exist? Metrical evidence won't do us any good here, since the doubled consonant would make the syllable long by position—but η and ω have their length shown clearly in writing.

Answer 1

There is the word γλῶσσα and a great number of other words derived from it. Here is a list of words containing -ωσσ-, giving more examples.

Answer 2

There are quite a few, actually. Just to add some more examples:

ἥττων "less"

πράττω "do" (impv. πρᾶττε shows the length)

πλήττω "strike"

μᾶλλον "more"

ἤλλαγμαι, pf. m./p. of ἀλλάττω "exchange"

ἡλλόμην, impf. of ἅλλομαι "jump"
