The main difference between Ladies and Women is that the Ladies is a term for a woman and Women is a female adult human
The word lady is a term of respect for a woman, the equivalent of gentleman. Once used to describe only women of a high social class or status, now it may refer to any adult woman. Informal use of this word is sometimes euphemistic (“lady of the night” for a prostitute) or, in American slang, condescending (equivalent to “mister”).
“Lady” is also a formal title in the United Kingdom. “Lady” is used before the family name of a woman with a title of nobility or honorary title suo jure (in her own right), or the wife of a lord, a baronet, laird, or a knight, and also before the first name of the daughter of a duke, marquess, or earl.
A woman is a female human being. The term woman is usually reserved for an adult, with girl being the usual term for a female child or adolescent. The term woman is also sometimes used to identify a female human, regardless of age, as in phrases such as “women’s rights”. Women with typical genetic development are usually capable of giving birth from puberty until menopause. There are also trans women (those who have a male sex assignment that does not align with their gender identity), and intersex women (those born with sexual characteristics that do not fit typical notions of male or female).
