SENTENCE_OPENERS

Words that may open a sentence without naming anything, read by Text.entityTokens.

English capitalizes the first word of every sentence, so a multi-sentence prompt hands the entity guard a capital that means nothing. Excusing all of them loses real entities — "…holiday. Austria is where I want to go." — so only words on this list are excused, and anything else that opens a sentence is still treated as a name.
