Definition
信誓旦旦 is a four-character idiom that literally means 'with a sincere and solemn oath.' It is most commonly used to describe lovers making earnest vows, often carrying a slightly sarcastic or skeptical tone — the speaker implies that the promises sound grand but may not be reliable. You can use it in contexts where someone's pledge seems too perfect or is given lightly.
f.e.
to make a solemn vow with great earnestness (often used ironically about lovers' promises)
