Final answer:
The word 'lascivious' means overly sexual in a lewd or indecent manner. This would closely align with the options 'wanton' or 'obscene'. It is often associated with legal and moral judgments concerning sexual decency.
Step-by-step explanation:
The meaning of the word 'lascivious' is associated with sexual desire in a way that is considered lewd or inappropriate. The best match among the options provided would be 'wanton' or 'obscene,' both of which imply a lack of restraint or decency in sexual matters. This word can be used to describe actions, expressions, or behavior that suggest a strong, often unscrupulous desire for sexual activity.
