Which expressions are commonly used.
Can we use 'actor' for a woman?

Yes. Actor applies to both men and women. Increasingly it is thought that men and women do not need to be separated by gender. An actor is an actor, like a doctor is a doctor, a truck driver is a truck driver, a teacher is a teacher, etc.

To determine which expressions are commonly used, we can analyze the given statements. Based on the information provided, we can observe the following:

1. "His father was an actor." - This statement indicates that the father had a profession as an actor.

2. "His mother was an actor." - This statement suggests that the mother also had a profession as an actor.

3. "His mother was an actress." - This statement provides an alternative term, "actress," which is the feminine form of the word "actor."

4. "Actors: Tom, John, Emily, and Susan." - This statement explicitly refers to individuals who are actors, and their names are provided.

5. "Actors and Actresses: Tom, John, Emily, and Susan." - This statement explicitly refers to both male and female individuals who are actors and actresses, and their names are provided.

From the given statements, we can deduce that it is common to use both "actor" and "actress" to refer to individuals who perform in theatrical or cinematic productions. Traditionally, "actor" has been used to refer to male performers, while "actress" has been used to refer to female performers. However, it is worth noting that there has been a growing trend to use the term "actor" as a gender-neutral term to refer to performers of any gender, and this usage has gained acceptance in some contexts.

In conclusion, it is commonly acceptable to use "actor" for both men and women, but using "actress" can also be used to specify the gender of the performer.
