Widow means a woman who has lost her husband by death and has not remarried. To be widowed is the act of losing your husband.
If a man and woman marries, have a child together and the mother dies, then the man becomes a widowed father.
When addressing a letter to a widowed woman, you can use "Mrs." followed by her late husband's last name, if she prefers that designation, or simply use her first and last name. For example, "Mrs. Jane Smith" or "Jane Smith." If you know she prefers not to use "Mrs." due to her status, you could address her as "Ms." followed by her name. Always consider her personal preference if you're aware of it.
If you do not know if the woman is single; married or widowed then you can use 'Ms.' If you know they are single then use 'Miss' or 'Ms.' and 'Mrs.' for married women or widowed women.
A widow is addressed as Mrs., unless she provides another preference.
The way to address an Italian gentleman begins with the word Signore ("Sir") in Italian.
The abbreviation in Italian for Mr. is "Sig." which stands for "Signore," and for Mrs. is "Sig.ra" which stands for "Signora." These abbreviations are commonly used in formal contexts in Italian language to address or refer to a man or a woman respectively.
"Strong woman" in English is virago in Italian.
