What are some vocabulary terms from Stardust?

Here are a few quotes from Stardust with some vocabulary words:

The inhabitants of Wall are a taciturn breed, falling into two distinct types: the native Wall-folk, as grey and tall and stocky as the granite outcrop their town was built upon; and the others, who have made Wall their home over the years, and their descendants.

Taciturn means hesitant to communicate or unwilling to talk. In this context, it sets up the Wall-folk as unfriendly and quiet.

It was festooned with flowers: bluebells and foxgloves and harebells and daffodils, but also with violets and lilies, with tiny crimson dog-roses, pale snowdrops, blue forget-me-nots and a profusion of other flowers Dunstan could not name. 

To festoon means to decorate, typically with hanging or dangling things such as ribbons, tinsel, or (in this case) garlands of flowers.

Tristran read it to himself, looking for something about which he could begin to talk: a conversational gambit of some kind—any kind.

A gambit is a risky strategy, action, or move used to gain advantage or to open up opportunity. Here, it means an icebreaker or a topic for small talk, a way for Tristan to naturally initiate conversation. Despite the similar sound and meaning, it is not etymologically related to the word "gamble."

“Redcap. They’ll keep their distance, but don’t you go scrutinizin’ ’em or looking for trouble, ’cos you’ll find it with those buggers.”

To scrutinize means to look at closely or carefully. In this case, the speaker is warning Tristan not to stare.
