An indirect suggestion is a way of suggesting something without explicitly saying it. INNUENDO, which is an 8-letter word, is a type of indirect suggestion that implies something with a double meaning. HINT, which is a 4-letter word, is another type of indirect suggestion that is more subtle than INNUENDO. ALLUDE, which is a 6-letter word, is another type of indirect suggestion that implies something without directly stating it. ROUNDABOUT, which is a 10-letter word, is another type of indirect suggestion that is more subtle than HINT or ALLUDE.
