Are there British English native speakers who glottalise their "t"s in the following words?
Into, its, after, still, student
The first case seems strange to me probably because "into" is like "in + to" and when a "t" starts a word, it never gets glottalised?
The "its" case seems strange to me, but I'm not sure why. Maybe because "ts" is pronounced like a single sound?
The last three seem like a rule: "ft", "st", "nt" never give in to glottalisation. But I made this rule up, I didn't find any rule like this online.
