// The mirror of checkFeminine, and the failure it was written for: the model

// herself.
//

// this looks for feminine past-tense words in a sentence that also talks TO him
// ("ты", "тебя", "тебе", "твой", …). A feminine verb that belongs to her ("я
// заметила", "напомнила тебе") is skipped — that one is correct.
//
// Honest about the limits: this is a suffix rule, not a parser.
// - False positives: a feminine noun can be the subject in the same sentence
// ("зарядка была утром, ты её пропустил"). The guard below skips a verb whose
// previous word looks like a feminine noun, which helps but will not always
// be right.
// - False negatives: gender also shows up outside the past tense (short
// adjectives, "сама"), and none of that is checked here.

// a grammar verdict, and every hit prints the word it tripped on so a human can
