"Hadst" is the archaic second-person singular form of "have," and is pronounced /hædst/. "Big" is pronounced /bɪɡ/, and "mouth" is pronounced /maʊθ/. Together, the phrase means "you had a big mouth," with the word "mouth" referring to someone who talks too much or reveals secrets. While not a commonly used phrase today, its spelling demonstrates the evolution of the English language over time.
"Hadst big mouth" is a phrase commonly used in informal language to describe someone who is overly talkative or known for divulging secrets or personal information without discretion. It is a playful or colloquial expression that emphasizes the idea of someone having a large or loud mouth, figuratively implying that they frequently speak or reveal things they shouldn't.
The term "hadst" is derived from the Middle English word "haddest," which is the second person singular form of the verb "to have" in the past tense. In this context, it suggests that the person being referred to possesses or owns a big mouth as an inherent or constant characteristic. The term "big mouth" is used metaphorically, indicating that the individual talks excessively or recklessly about others or themselves.
This expression is often employed humorously or somewhat mockingly to tease or criticize someone who has a tendency to gossip, spread rumors, or disclose private information. It highlights their inability to keep secrets and implies a lack of discretion or self-control when it comes to sharing information. The phrase "hadst big mouth" is not intended to be literal but rather serves as a lighthearted way of referring to someone who tends to be outspoken, revealing, or indiscreet in their speech.
