The transition words
are used to link words, phrases or sentences in order to help the reader to
progress from one idea to the next idea. They also help to build up coherent
relationships within the text. Transition words have been assigned to
artificial categories such as: agreement, opposition, causes, examples, effect,
conclusion etc.
In the first sentence
transition word is “and” (“…bespoke repression and even a certain strength”) which
belongs to the category of agreement transition words (alongside again, then,
also…)
In the second sentence
transition word is “but” (“But now there was a dull stare in her eyes…”) which
belongs to the category of opposition (alongside still, unlike, yet, while…),
whose gaze was fixed away off yonder on one of those patches of blue sky. 
<span>In the third sentence is
the transition phrase “but rather” (“…but rather indicated a suspension of
intelligent thought”), in category of opposition.</span>
