[General] Glottal vs glottalized variants of (t)

[darira]

Hello everyone, I was writing my dissertation on the glottal stop and I found this in a paper: "There is a slight tendency for young females to favour glottal (as opposed to glottalized) variants of (t)".
So my question is : what is the difference between the terms glottal and glottalized ?

I hate to intrude, but how can /t/ be glotal or glottalized at all? It's an alveolar consonant.

It's not an alveolar consonant when it's glottalized.
